摘要
通过稳态荧光光谱滴定和紫外 可见光谱考察了5 (对羧基苯基 甲酰氨基)苯基 10,15,20 三苯基卟啉(p CPTPP)锌(Ⅱ)、铜(Ⅱ)配合物体系通过氢键的超分子自组装行为。在荧光光谱滴定中,当Cu(p CPTPP)浓度在一定范围内时,随着Cu(p CPTPP)浓度增大,Zn(p CPTPP) Cu(p CPTPP)体系荧光强度逐渐增大并稍有红移。根据荧光光谱滴定数据计算了超分子的结合常数,由小波变换方法分解得到的超分子电荷分离态荧光光谱解释了体系荧光增强现象。
The supramolecular selfassembly behaviors by hydrogenbonding of zinc(Ⅱ)(Zn(Ⅱ)(pCPTPP)),copper(Ⅱ)(Cu(Ⅱ)(pCPTPP)Cl)complexes of 5(4carboxy)phenylenemethanaminophenyl10,15,20triphenylporphyrina(pCPTPP)were studied by fluorescence spectroscopic titration and UVVis spectra.When the concentration of Cu(pCPTPP)is lower,the system Zn(pCPTPP)Cu(pCPTPP)possess the fluorescence strengthening character.The association constant was determined from the data of fluorescence spectroscopic titration and the fluorescence strengthing property of the system was discussed using the fluorescence spectrum of the chargeseparated state obtained by the method of spline wavelet least square.
