摘要
采用紫外G可见吸收光谱（UVGVis）、红外光谱（IR）、扫描电镜（SEM）技术探讨了瓜环Q[7,8]与具有光动力疗效的光敏剂四苯基卟啉锌（ZnTPP）分子之间的组装作用.结果表明,Q[7,8]与ZnTPP均形成以1∶1为主的组装物;溶液pH 值在5.0-11.0范围内,组装体较稳定;主G客体间的相互作用都能够自发进行,组装过程是放热反应,以熵驱动为主;与ZnTGPP相比,组装体的荧光量子产率并没有明显下降;ZnTPP与Q[7,8]组装后,溶解度得到极大的提高.
The functional assembly between Q[7],Q[8]with zinc tetraphenylporphyrin( Zn TPP) were investigated by ultraviolet-visible absorption spectrum,infrared spectrum and scanning electron microscopy. The results show that the assembly rate was about 1∶ 1 respectively between Q [7,8]and Zn TPP; when p H value of solution was in the range of 5.0-11. 0,assembly was more stable; the thermodynamic data shows that assembly process was spontaneous,exothermic,and giving priority to entropy driven; fluorescence quantum of assembly was not significantly decreased when compared with Zn TPP; the solubility of Zn TPP have been improved extremely as a result of assembled with Q [7,8].
