合成了阳离子型、两性离子型和阴离子型的噻菁染料,对它们的结构进行了表征,并研究了染料的结构(阴离子和取代基的改变) 对吸收光谱的影响。

关键词: 吸收光谱法, 取代基效应, 增感染料, 噻菁染料

Cationic, zwitterionic and anionic thiacyanine dyes were synthesized and characterized. The compounds containing fluoro or trifluoromethyl substituents were reported. Their UV-vis and IR spectra were measured. The effect of anion and substitutent an λ ~m~a~x and μ~m~a~x were examined.

Key words: SUBSTITUENT EFFECT, ABSORPTION SPECTROMETRY
