摘　　要：在水/二甲基亚砜(DMSO)的混合溶液体系中,利用自组装方法,使5,10,15,20-四苯基卟啉铟(InTPP)分子聚集成纳米材料,并研究了其最优制备温度为50℃。通过场发射扫描电子显微镜(FE-SEM)对铟卟啉纳米材料的表面形貌进行了研究,可获得粒径为100～200nm的棒状铟卟啉纳米材料。利用紫外-可见光谱分析了铟卟啉单体与纳米材料光学性质的差别:在紫外-可见光谱中,铟卟啉纳米分散体系的Soret带吸收峰从原来的423nm分别红移到433和453nm,吸光值明显减小,峰形呈劈裂状且明显变宽。利用紫外-可见光谱对铟卟啉的光学检测性能进行了研究,将铟卟啉单体和纳米溶液体系对低浓度甲基膦酸二甲酯(DMMP)的检测效果进行了对比,结果显示铟卟啉纳米溶液体系的检测效果明显优于单体。The 5,10,15,20-tetraphenylporphyrin indium（InTPP）molecule was aggregated to be nano-material in the water/dimethylsulfoxide mixed solution by self assembly approach.We investigated the optimum temperature was 50 degrees centigrade.The structure and surface morphology of the nano-InTPP were characterized by field emission scanning electron microscopy（FE-SEM）.The optical properties of nano-InTPP were characterized by UV-Vis spectrometer.The FE-SEM results showed the morphology of nano-InTPP was rodlike,the size of nano-InTPP was approximate 100-200nm and the distribution of nanoparticles was homogeneous.Comparing the UV-Vis spectras of the monomer with that of the nano-InTPP,it was shown that spectra the Soret band of monomer at 423nm was split into two red-shifted bands at 433 and 453nm respectively in UV-Vis,the absorbance of Soret band was significantly reduced and the shape of soret band was obviously widened.The detection optical properties of indium porphyrin had been studied by UV-vis spectra.Comparing the detection results of the monomer with that of the nano-InTPP,it was shown the detection results of nano-InTPP were obviously better.
