The soluble polythiophenes functionalized with a non-linear optical chromophore were prepared using copolymerization. The microstructure and the composition of the copolymers was determined through nuclear magnetic resonance spectroscopy. Two different types of solvent effects were identified. The first effect was on the conformation of the thiophene backbone and the other was on the electronic transition energy of the azobenzene unit.

Abstract
The soluble polythiophenes functionalized with a non-linear optical chromophore were prepared using copolymerization. The microstructure and the composition of the copolymers was determined through nuclear magnetic resonance spectroscopy. Two different types of solvent effects were identified. The first effect was on the conformation of the thiophene backbone and the other was on the electronic transition energy of the azobenzene unit.File in questo prodotto:
