Abstract
Complicated nanopattern composed of crosswise aligned nanoribbons of the supramolecular assemblies of a triangular molecule, tri-l-(glutamic diethyl ester)-1,3,5-benzenetricarboxamide (T-l-Glu-BB), can be easily constructed by the extremely simple Langmuir-Blodgett (LB) process. The application of such nanopattern by templated chemical polymerization strategy to integrate anisotropically aligned polypyrrole (PPy) nanoparticles is described. We have showed that not only parallel arranged but also crosswise aligned PPy nanobelts composed of anisotropically arranged nanoparticles of the polymer can be integrated easily over large area silicon surface. More importantly, the width of the parallel aligned PPy nanobelts and the interspace between them can be dexterously regulated to some extent by using distinct silicon substrates that have different hydrophobicities or by altering the synthesis process. A plausible mechanism has been proposed for the described strategy.
