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