Hagimori, Masayori;Yoshida, Tatsusada;Nishimura, Yasuhisa;Ogawa, Yukiko;Tanaka, Keitaro research published 《 Syntheses of novel pyridine-based low-molecular-weight luminogens possessing aggregation-induced emission enhancement (AIEE) properties》, the research content is summarized as follows. Novel pyridine-based fluorescing compounds, viz. pyrido[1,2-a]pyrrolo[3,4-d]pyrimidines I [R = H, Me] and N-methyl-4-((pyridin-2-yl)amino)maleimides II [R1 = F, CN, Br, etc.] were selectively prepared by a one-pot reaction between a functionalized maleimide and 2-aminopyridines with electron-donating or electron-withdrawing groups at position 5 and were investigated photophys. and computationally. The photophys. studies revealed that all the synthesized compounds I and II exhibited fluorescence in organic solvents, while compounds II, which were based on an acceptor-donor-acceptor (A-D-A) system, exhibited aggregation-induced emission enhancement (AIEE) properties in aqueous media. Compounds II [R1 = Br, CF3] showed 7.0 and 15 times fluorescence enhancement. Time-dependent d. functional theory (TD-DFT) calculations were performed to gain better insight into the electronic nature of the compounds I [R = H] and II [R1 = Br, CF3] with and without AIEE properties.
