Recent progress in novel luminescent materials based on mechanically interlocked molecules
In recent years,along with the rapid development of mechanically interlocked molecules(MIMs),the introduction of luminescent elements into MIMs and the further explorations on their unique luminescence properties have attracted more and more attention.Compared with small luminescent molecules,the existence of mechanical bonds endows the resultant emissive MIMs with attractive luminescent properties.In addition,taking advantage of the unique dynamic feature of MIMs,the further construction of a variety of luminescent MIMs with stimuli-responsive emission behaviors have been successfully realized,which have showed wide potential applications in the fields of photocatalysis,optical sensing,and smart luminescent materials.Notably,the further introduction of chiral elements into mechanically interlocked luminescent molecules results in the successful construction of novel circularly polarized luminescence(CPL)-active materials.In this review,we summarized the recent research progress of mechanically interlocked luminescent molecules from the following three aspects:the regulation of luminescent properties through mechanical bonds,stimuli-responsive mechanically interlocked luminescent materials,and CPL-active chiral mechanically interlocked molecules,analyzed the current challenges,and prospected the future development directions in this field.
