Abstract

A novel whole-rainbow-color (403 ≤ λmax ≤ 655 nm) organic solid fluorophore system was synthesised from subtle modification of a single-core structure of thiazolo[5,4-b]thieno[3,2-e]pyridines at a single site. The photoproperties and single-crystal packing structures were systematically investigated. Fifteen aggregation-induced emission luminogens (AIEgens) were obtained with a high photoluminescence efficiency (quantum yield (ΦF) as high as 63%), and 2 solid/solution dual fluorophores also were identified with ΦF greater than 20% (in tetrahydrofuran, in benzene and in the solid state). In addition, a deep-red-emissive compound (λem = 655 nm) was obtained via intermolecular self-assembly and extension of conjugation through intramolecular H-bonding.
