Abstract :
Electroactive Langmuir-Blodgett (LB) films have been assembled from mixtures of poly(3-alkyl thiophenes) and stearic acid. Stable monolayers and highly ordered multilayers were formed with varying alkyl chain lengths from four carbons to eighteen carbons. X-ray diffraction revealed that the multilayers form well-defined two-dimensional structures. X-ray absorption experiments revealed that the polythiophene backbone is disordered in a matrix of highly ordered and vertically oriented stearic acid molecules. With long (eighteen carbon) alkyl chains, the chains were oriented along the stearic acid molecules
