Abstract

Conjugated polymers are characterized by the delocalization of ?-electrons responsible of their electrical properties and structural rigidity. The manipulation of the chemical structures through the introduction of flexible chains allows to influence the morphology controlling the nanosegregation of the material.The use of nanocrystals (NCs) of inorganic semiconductors in "hybrid solar cells" offers high electron mobility enhancing the performance of the devices. The control of the active layer morphology at the nanoscale level ensures the further improve of the efficiency of the cells.The goal of this work is the evaluation of two approaches for the synthesis of a rod-coil copolymer based on poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] rod-like block (electrondonor) and a coil block of poly(4-vinylpyridine) able to interact with semiconducting CdSe NCs (electronacceptor) with the aim of using it as both active and coordinating material for nanocomposites preparation with over 90% of NCs.
