title = "{\"I} -conjugated naphthodithiophene homopolymers bearing alkyl/alkylthio-thienyl substituents: Facile synthesis using hexamethylditin and their charge-transport and photovoltaic properties",
abstract = "Two -conjugated naphtho[1,2-b:5,6-b']dithiophene (NDT)-based homopolymers functionalized with alkyl-thienyl or alkylthio-thienyl side chains were designed and synthesized via palladium-catalyzed dehalogenative polycondensation using hexamethylditin as the condensation reagent. Their photophysical properties and device performances for organic field-effect transistors and organic solar cells were systematically studied. Replacing lateral alkyl-thienyl substituents with alkylthio-thienyl ones led to better photoabsorption properties and a deeper-lying HOMO energy level of the resulting NDT homopolymers. The alkylthio-thienyl-functionalized NDT homopolymer showed a higher hole mobility and superior photovoltaic properties compared with the alkyl-thienyl homolog.",
