在水/乙醇混合溶液体系中,利用自组装方法,使5-对磺酸基苹基-10,15,20-三苯基卟啉(TPPS1)分子聚集成功能化卟啉纳米材料.利用AFM、SEM、FE-SEM对卟啉纳米材料表面形貌性质及样品处理条件进行了研究:可获得50～70nm不同粒径的卟啉纳米材料;通过控制、调节样品的处理条件,可实现纳米材料尺寸的可控.利用紫外可见光谱和荧光光谱分析自组装卟啉与卟啉单体光学性质的差别:在紫外-可见光谱中,自组装卟啉Soret带吸收峰从原来的412nm分别蓝移和红移到361和451nm,呈现明显的劈裂状,且峰形变宽.以上特征性变化预示了卟啉纳米材料的形成;在荧光光谱中,纳米卟啉的荧光强度以及荧光量子产率分别约为未纳米化TPPS1单体的4和3倍,体现出良好的光敏性能,可作优良的光敏元件及光敏材料.
