A series of 1,3-thiazole-based organoboron complexes has been designed and synthesized by acylation of 2-amino 4-subsituted 1,3-thiazoles with (4-dimethylamino)benzoyl chloride and the subsequent BF2 complexation reaction. The influence of substituents in position 4 of the thiazole ring on photophysical properties of the complexes has been investigated. Synthesized thiazolo[3,2-c][1,3,5,2]oxadiazaborinines
通过将2-氨基4-取代的1,3-噻唑与(4-二甲基氨基)苯甲酰氯酰化并随后进行BF 2络合反应,设计并合成了一系列基于1,3-噻唑的有机硼配合物。研究了噻唑环4位上的取代基对配合物光物理性质的影响。合成的噻唑并[3,2- c ] [1,3,5,2]恶二氮杂嘌呤主要在溶液中显示出强烈的荧光。具有4,5-未取代噻唑单元的配合物表现出聚集诱导发射(AIE)效应,并且由于抑制了分子中的π–π / π– n相互作用,因此在固态下具有很高的荧光量子产率(94%)包装。
