structurally well-defined triarylethene-based extendedπ-systems have been prepared very rapidly. From a compound library constructed by the present method, it was possible to find a number of interesting fluorescent materials, as well as interesting fluorescent properties such as aggregation-induced enhanced emission. A useful method for the rapid synthesis and property evaluation has also been developed
A series of 1,4-bis[2,2-bis(4-alkoxyphenyl)vinyl]benzene molecules with aggregation-induced emission (AIE) activity were synthesized. The conformations and packing arrangements of these molecules in the solid state can be adjusted by changing the side chains, which subsequently modulates their solid-state emission. The fluorescence quantum yield of 1e with the n-C(6)H(13) side chain in the solid state could reach up to 60.3% in the solid state.
