合成了2种含萘酰亚胺功能基元的吡唑啉酮席夫碱化合物:1-苯基-3-甲基-4-苯甲酰基毗唑啉躺缩N-(4—氨基苯基)-4哌啶-1,8礤酰亚胺(Ⅰ)和1—苯基-3-甲基-4—苯甲酰基毗唑啉酮-5缩4-阱基-N-十二烷基--1,8-萘酰亚胺(Ⅱ),对其在不同溶剂中的光谱性质进行了研究,发现席夫碱Ⅱ表现出了特殊的溶致变色效应;对席夫碱Ⅰ和Ⅱ在不同pH值的乙醇水溶液中的光谱性质研究发现,席夫碱Ⅰ的光谱性质受质子影响甚微,而席夫碱Ⅱ对质子表现出紫外吸收和荧光发射双重光响应.
Two new schiff base 1 -phenyl-3 --methyl-4 -benzoyl-pyrazolone-5 p-aminophenyl-4 -piperidinyl -1,8--naphthalimide ( Ⅰ ) and 1 -phenyl-3 -methyl -4 -benzoyl -pyrazolone-5 4 -hydrazine-N --dodeeyl-1,8 - naphthali-mide ( Ⅱ ) were synthesized, and the spectrum properties of compounds I and Ⅱ in different solvents were investigated. The compound Ⅱshows special solvatochromism in different pH ethanol/water solutions. The spectrum of compound Ⅰ can hardly be affected by proton. But the compound of Ⅱ behaves double p-hoto- response (UV and fluorescence) to proton, and it also behaves acidi-chromism and basie-chromism and e-xhabits performance of fluorescent molecule switch and chemsenors.
