摘要：

It was found that 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin (TPPS), which is known to aggregate in a one-dimensional direction in water, acted as a template for electrochemical polymerization of aniline on ITO electrode. Examinations using cyclic voltammetry (CV) and UV-vis spectroscopy established that J-aggregated TPPS molecules were entrapped in the resultant poly(aniline). Scanning electron microscopy (SEM) observation established that poly(aniline) grew up to a nanosized rod-like structure, reflecting the aggregation structure of TPPS. It is a very novel and important finding that poly(aniline), which has been believed to result in only "rigid" film, can be morphologically controlled using a "template method".
