摘要
卟啉作为自然界的关键功能染料,在光合作用、呼吸载氧等过程中扮演着重要角色.卟啉具有独特的配位空腔和二维共轭骨架,光电性质优异,成为构建有机功能染料的重要平台.然而,常规卟啉的共轭回路为 18π,近红外区的光谱响应弱,在一定程度上限制了应用拓展.为此,研究人员开发了多种在卟啉外围稠合芳环的方法,来扩展分子共轭并提升长波长区域吸收与发光.本文总结了β,β-和meso,β-两类芳香稠环卟啉的典型合成方法,对比了稠环种类、数目、方式等对长波长光谱响应的调控作用.同时,本文还简要介绍了芳香稠环卟啉在自组装、芳香性/反芳香性调控、稳定自由基、自旋电子学应用等方面的研究进展.最后,从合成与应用角度展望了芳香稠环卟啉的未来研究方向.
Abstract
Porphyrins are crucial pigments in natural systems,and play key roles in photosynthesis,O2 transportation,etc.Considering their unique chelation cavity and planar π-framework as well as the remarkable optoelectronic and redox properties,porphyrins provide an important platform for synthesizing functional pigments.However,regular porphyrins feature 18π-conjugation system and possess inferior spectral response in the near-infrared(NIR)region,limiting the further development of applications.Many strategies have been developed to fuse aromatic system on the peripheral of porphyrins with aim of extending the conjugation skeletons and improving the absorption and emission in NIR region.In this review,we would like to summarize some typical methods in construction of β,β-and meso,β-aromatic group fused porphyrins.The maxima of absorption or emission will be listed to learn the influence of the responsive in long wavelength by the type,number and fusion-mode of aromatic units.Meanwhile,the effect of annulation on the self-assemblies,aromaticity/antiaromaticity regulation,radical stabilization,spintronic property etc will be described.In the end,we outlook the further developments of such ring-fused porphyrins in terms of synthesis and applications.
