Novel chromophores from alternated pyridine-ethylenedioxythiophene unit oligomers: dramatic enhancement of photoluminescence properties in elongated derivatives

Chem Commun (Camb). 2009 Feb 14:(6):692-4. doi: 10.1039/b815656e. Epub 2008 Dec 12.

Abstract

Novel chromophores based on the alternation of electron-poor (pyridyl) and electron-rich (ethylenedioxythienyl) heterocycles were synthesized for the first time and shown to exhibit attractive optical properties in relation with their specific electronic and geometrical (coiled structure) features.
