Their photophysical, both in solution and in the solid state, and structural properties were investigated. The influence of donor and acceptor substituents (R) in the benzothiazole unit on photophysical properties of complexes was found out. The tetrafluorobenzothiazole analogue exhibits nonbonded nuclear spin–spin coupling between fluorines from the BF2 group and α-fluorine atom at the benzene ring
设计并合成了与供体4-二甲基氨基苯基共轭的高发射苯并[4,5]噻唑并[3,2- c ] [1,3,5,2]恶二氮杂嘌呤家族。研究了它们在溶液和固态下的光物理性质和结构性质。发现了苯并噻唑单元中的供体和受体取代基(R)对配合物的光物理性质的影响。四氟苯并噻唑类似物在BF 2基团的氟与苯环上的α-氟原子之间表现出未键合的核自旋-自旋耦合。此外,该硼配合物显示出较高的固态荧光量子产率(Φ= 0.34)。
