摘要
4 异丁氧基邻苯二腈与氯化镍在强有机碱 1 ,8 二氮杂双环 (5 ,4,0 )十一碳烯 7催化下反应 ,合成了四异丁氧基镍酞菁 ,产物经FT -IR、元素分析、UV -Vis吸收光谱和1 H NMR表征了结构 ;并研究了其溶剂效应 ,结果表明 :最大吸收峰波数ν与函数 f(n ,ε)存在一定的线性关系 ,线性相关系数为 0 940 2 ,而Bayliss函数项 (n2 - 1 ) /(2n2 +1 )决定了最大吸收波长 (λmax)的位移变化 ;化合物的λmax在不同溶剂中随聚集程度增加 。
Nickel tetra(isobutoxy)phthalocyanine was prepared from 4 isobutoxyphthalodinitrile and anhydrous nickel chloride in anhydrous solvent of 1 pentanol catalyzed by 1,8 diazabicycloundec 7 ene (DBU) .Its structure was confirmed by FT-IR,UV-Vis, 1H NMR and elementary analysis.Solvent effect of the compound in eleven different solvents was studied.It was found that the wave number of the compound was dependent on the function f(n,ε ) with good linearity (correlation coefficient=0 9402),but it was mainly related to Bayliss function.The maximum absorption wavelength ( λ max ) had a tendency of blue shift with increasing molecular aggregation in different solvents.
