摘要
本研究以2,7-二噻吩芴衍生物为基础,引入Br进行改性,以获得性能优良的UV吸收剂,并通过MS和NMR对产物进行结构表征,并利用UV-Vis和PL对产物的紫外光吸收性能及发光情况进行研究。结果表明,当引入四个溴原子时,C2薄膜的最大UV吸收峰位于290~420nm之间,而荧光相对强度接近于0,是具有应用潜力的紫外光吸收剂。
The research aimed to obtain excellent UV absorbents based on 2,7-di（4-hexylthiophen-2-yl）-9H-fluorene by modifying with bromine atoms, we underwent the structural characterization of resulting compounds by MS and NMR, investigated their UV light absorption and fluorescence emission via UV-Vis and photoluminescence （PL）. Results indicated that after introducing 4 Br atoms, the thin film of C2 showed maximum absorption during 290-420 nm, with almost zero relative PL intensity, is a potential UV light absorbent.
