π-Conjugated organic luminescent materials are essential components for modern optical and photoelectric research.This review mainly probes into the recent work in the progress of smart π-conjugated organic systems in the form of cyanostilbene and its derivatives,which can regulate its excellent features in response to a variety of physical or chemical stimuli(e.g.viscosity,light,magnetism,electric field,polarity,pH and solvent environment).As a result of its extensive applicability and adaptability,cyanostilbene and its derivatives have been planted into different structural architectures such as polymers,functional nanoparticles,solid membranes,supramolecular systems and so on.This review will first give a general description of the preparation and characterization of cyanostilbenebased optoelectric luminophores and then focus on their peculiar functional properties in the need for advanced material applications,such as AIEE(aggregation-induced enhanced emission effect),solidstate emission,photovoltaics,photolithography and photochromism to be further processed afterwards.The purpose of this review is to give a platform of practical organic materials,mostly cyanostilbene and its derivatives,based on stable aromatic derivatives,to contribute to the booming of modern π-conjugated photoelectric materials that integrate with contemporary physics,material chemistry,bioengineering,medical science and aerospace altogether. π-Conjugated organic luminescent materials are essential components for modern optical and photoelectric research.
