Purely organic luminophores that exhibit room temperature phosphorescence (RTP) are receiving an ever-growing attention. The design of efficient RTP materials and the understanding of their emissive behavior, however, remain a challenging task. Herein, to gain further insights into metal-free RTP, we report the synthesis, characterization, and photophys. study of chloro-derivatives of [1,2-a:1′,2′-c:1”,2”-e][1,3,5]triazine or cyclic triimidazole (TT). Mono- (1Cl), di- (2Cl) and tri-chloro-TT (3Cl) derivatives are prepared by mild chlorination with N-chlorosuccinimide (NCS). The three compounds are characterized by aggregation-induced emission (AIE) comprising dual fluorescence and multiple phosphorescences, whose origin is disclosed by crystal structure anal. together with accurate DFT/TDDFT calculations Comparison with previously reported bromine and iodine TT derivatives reveals the new chlorinated compounds as the best performing halogenated AIE members of the family.
European Journal of Organic Chemistry published new progress about Aggregation-induced emission. 128-09-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C4H4ClNO2, Reference of 128-09-6.
