    N,O-Bidentated difluoroboron complexes based on pyridine-ester enolates:Facile synthesis,post-complexation modification,optical properties,and applications

    Chaochao JinKai LiJiongpei ZhangZhihua Wang...
    169-174页
    查看更多>>摘要：An array of pyridine-ester enolate based organoboron complexes has been designed and synthesized via a one-pot cascade of Pd-catalyzed α-arylation and BF2 complexation.The rapid structure-activity relation-ship(SAR)studies indicated that unsymmetrical N,O-chelated BF2 complexes were highly fluorescent in solid state,and exhibited large Stokes shifts,excellent photostability,along with insensitivity to pH.Theα-aryl group could not only modulate the electronic effect but also inhibit the intermolecular π-π stack-ing to promote the aggregation-induced emission(AIE)effect.DFT calculations and experiments identi-fied that the intramolecular charge transfer properties of these N,O-chelates could be switched by the modification of substituents,resulting tunable fluorescence wavelengths.Furthermore,post-complexation modification was accomplished,including Suzuki-Miyaura cross-coupling,Buchwald-Hartwig amination,oxidative cleavage,along with a unique triple substitution reaction involving propargyl Grignard reagents.The exemplificative application of dimethylamine substituted boron complex as a reversible acidic vapor sensor was also demonstrated.

    Anthracene-bridged"Texas-sized"box for the simultaneous detection and uptake of tryptophan

    Dan LuoJinya TianJianqiao ZhouXiaodong Chi...
    175-178页
    查看更多>>摘要：Tryptophan(Trp)is an essential amino acid that plays a critical role in human physiology.The increasing demand for Trp has created a highly promising market,underscoring the urgent necessity for the devel-opment of efficient strategies for the simultaneous detection and uptake of tryptophan.Herein,we report an expanded"Texas-sized"molecular box(AAn-TxSB),which incorporates luminescent anthracene bridg-ing subunits and molecular recognition motifs.This luminescent molecular box demonstrates exceptional sensitivity to Trp in water,permitting its precise quantification with a notably low limit of detection(LOD)of 0.42 μmol/L.Moreover,An-TxSB facilitates the proficient uptake of Trp from simulated water samples,thereby revealing an impressive Trp adsorption capacity of up to 226.0 μmol/g.

    Pillar[5]arene based artificial light-harvesting supramolecular polymer for efficient and recyclable photocatalytic applications

    Lei ZhouYoujun ZhouLizhen FangYiqiao Bai...
    179-182页
    查看更多>>摘要：Photosynthesis is the process through which living plants utilize photosynthetic pigments,such as chloro-phyll,to convert CO2 and water into organic compounds and release O2 under visible light.In this study,we have successfully constructed a fluorescent supramolecular polymer(P5Py2/Zn/Gen)n by em-ploying orthogonal pillar[5]arene-based molecular recognition and metal ion coordination.Within the supramolecular polymer,the guest molecule Gen unit acts as a light-harvesting moiety,as the ACQ effect is inhibited by host-guest interactions,while the(Py)2/Zn center serves as a catalytic site.By employing this orthogonal self-assembly strategy,we have enhanced the stability of both the donor and acceptor in catalyzing the reduction of p-nitrophenol to p-aminopheno.Moreover,this photocatalyst can be reused at least 5 times without significant conversion loss.These findings provide a pathway for constructing a recyclable artificial LHS that mimics the entire photosynthesis process.

    Luminescent terphen[3]arene sulfate-activated FRET assemblies for cell imaging

    Zhixue LiuHaiqi ChenLijuan GuoXinyao Sun...
    183-186页
    查看更多>>摘要：Multicharged supramolecular assemblies based on luminescent macrocycle play an important role in extending their optical properties and functions.Herein,we reported macrocyclic supramolecular as-semblies based on luminescent terphen[3]arene sulfate(TP[3]AS)and tetraphenylethylene pyridinium(TPE-4Py)through electrostatic interactions,host-guest encapsulation and π-π stacking interactions.Förster resonance energy transfer(FRET)process from TP[3]AS to TPE-4Py was achieved with the en-ergy transfer efficiency of 99.9％,accompanied by TPE-4Py fluorescence emission bathochromic shifted of 15 nm and enhanced by 1.68 times in PBS solution.In contrast,other non-luminescent sulfato-β-cyclodextrin and sulfobutylether-β-cyclodextrin only can enhance the fluorescence intensity of TPE-4Py without bathochromic shift.Due to the strong fluorescence and good stability of TPE-4Py@TP[3]AS,it can be used for optical imaging in living cells,which provided an effective approach for the construction of assembling-confined luminescent biomaterials.

    Laser constructed vacancy-rich TiO2-x/Ti microfiber via enhanced interfacial charge transfer for operando extraction-SERS sensing

    Ying HouZhen LiuXiaoyan LiuZhiwei Sun...
    187-192页
    查看更多>>摘要：Semiconductor-molecule surface-enhanced Raman scattering(SERS),especially the stronger interfacial charge transfer process(ICTP),represents a frontier in the field of SERS with spectral reproducibility and unparalleled selectivity.Herein,through a laser microfabrication method in situ,the free-standing,super hydrophilic and vacancy-rich TiO2-x/Ti is successfully synthesized.Using blue TiOx/Ti(B-TiOx/Ti)as pre-concentrated substrate,a nanomolar-level limit of detection of 12nmol/L at 1385 cm-1,is confirmed using crystal violet(CV)bacteriostat as a model under 532 nm excitation.Furthermore,the results demonstrate that the SERS enhancement mechanism is via the moderate adulteration of oxygen vacancy,which leads to a narrow value of band gap and increases the ICTP of substrate to molecules.Using a hand-held ex-tractor assembled with B-TiOx/Ti microfiber,the operando analysis of mixtures distributed information excited in different parts of Asian carp is facilely achieved.This work guides the controlled synthesis of vacancy-rich TiO2-x/Ti nanostructure and its application in ultrasensitive extraction-SERS detection.It also provides the direction for the rapid and operando transmission of biological information with temporal and spatial concentration distribution in human tissues by highly sensitized materials.

    Surface doping effect on the optoelectronic performance of 2D organic crystals based on cyano-substituted perylene diimides

    Jaeyong AhnZhenping LiZhiwei WangKe Gao...
    193-197页
    查看更多>>摘要：Compared to organic thin films,organic single crystals offer significant potential in organic phototransis-tors(OPTs)due to their enhanced charge transport,large surface area,and defect-free nature.However,the development of n-type semiconductors has lagged behind p-type semiconductors.To enhance semi-conductor device performance,a doping process can be employed,which typically involves the introduc-tion of charged impurities into the crystalline semiconducting material.Its aim is to reduce the Ohmic losses,increase carrier density,improve transport capabilities,and facilitate effective carrier injection,ul-timately enhancing the electrical properties of the material.Traditional doping processes,however,often pose a risk of damaging the structure of single crystals.In this study,we have synthesized novel cyano-substituted chiral perylene diimides,which self-assemble into two-dimensional single crystals that can be used for n-type semiconductor devices.We have employed a surface doping strategy using diethy-lamine vapor without disrupting the crystal structure.The fabricated devices exhibit significantly higher charge transport properties after doping,achieving a maximum electron mobility of 0.14 cm2 V-1 s-1,rep-resenting an improvement of over threefold.Furthermore,the optoelectronic performance of the doped devices has significantly improved,with the external quantum efficiency increased by over 9 times and the significantly improved response time.These results suggest that our surface doping technology is a promising way for enhancing the performance of 2D organic single-crystal OPTs.

    On-surface photo-induced dechlorination

    Yu HeHao JiangShaoxuan YuanJiayi Lu...
    198-201页
    查看更多>>摘要：On-surface Ullmann-type reaction,or the dehalogenated coupling,is arguably the most pivotal reaction in on-surface synthesis for the fabrications of carbon nanostructures.Hitherto,the vast majority of works rely on activating the C-Br bond of aryl bromide which has a moderate bond dissociation energy.The C-Cl bond of aryl chloride has a higher dissociation energy and requires much higher thermal energy to break the bond.In this study,we have explored the on-surface photo-induced dechlorination and achieved the activation of three distinct aryl chlorines on the Au(111)surface with mild temperatures.This work enriches our understanding of on-surface photo-induced reactions and highlights the potential of photochemistry in realizing unconventional reactions.
