Unusual Solvatochromism of a New Conjugated Polymer Containing Oxadiazole.
The spectroscopic properties of a new synthesized conjugated polymer constituted of 3,3′-didecyl-2,2′-bithiophene and 2,6-di-1,3,4-oxadiazole-toluene moieties in the mixed solvent system of chloroform (solvent for the polymer) and methanol (non-solvent for the polymer) were studied. An unusual solvatochromism either in absorption or in emission was observed for the first time on conjugated polymers containing oxadiazole.
