摘　　要：本研究以有机太阳能电池聚合物给体材料的中间体2,7-二(4-正己基噻吩)-9H-芴为基础,在噻吩环上引入溴原子进行修饰,以猝灭其荧光,从而获得相应的紫外线吸收剂,并通过基质辅助激光解吸电离飞行时间质谱及核磁共振谱等对产物进行表征,并利用紫外可见光光谱和分子荧光光谱对产物的光谱性质进行研究。结果表明,引入溴原子数目越多,荧光强度越低,更适合作为紫外光吸收剂。The piece of work based on 2,7-di（4-hexylthiophen-2-yl）-9H-fluorene, the precursor of polymeric donor material in organic solar cells, the bromine atoms were introduced into the thienyl ring, to quench the fluorescence of the precursor, to obtain relative UV absorbents, characterizations were undergone on the resulting compounds by MOLDI-TOF MS and NMR, the photophysical properties of resulting compounds were investigated by UV-Vis and molecular fluorescence spectra. Results indicated that the more bromine atoms are introduced, the lower fluorescent intensities are obtained and better for the application of UV absorbent.
