The effect of cyano and methyl substitution on the fluorescence behavior of 1,2-bis(pyridylphenyl)ethene 1-4 was investigated(Figure 1).1 While non-substituted 1,2-bis(pyridylphenyl)ethene 1 has fluorescence quantum yield of 97 ％in CH2Cl2 solution,cyano-and methyl-substituted ones 2-4 fluoresce very little.

Mechano-responsive luminescent materials are a class of "smart" materials with fluorescent properties that change in response to external force stimuli.These materials are widely used in sensors,memor
Room temperature phosphorescent(RTP) have been observed in organic crystals of non-planar molecules containing carbonyl groups,1 which is induced by crystallization(CIP).Thus mechanochromic or thermoc
The materials with aggregation induced emission(AIE) were important in luminescent materials because they could solve the aggregation caused quenching of chromophore.
An idea of absolute asymmetric synthesis(AAS),controlled synthesis of desired chiral molecule using circularly polarized light(CPL) source without chemical influence,was first predicted by Le Bel(1874
Because restricted molecular rotation is the inherent mechanism responsible for the aggregation-induced emission(AIE) of propeller-shaped luminogens,1 intermolecular hydrogen bond(H bond) interactions
