Abstract

A solution-processed small molecule utilizing a novel 4,9-bis(2- ethylhexyloxy)naphtho[1,2-b:5,6-b′]dithiophene zig-zag core (zNDT) exhibits high hole mobility, upshifted frontier MO energies, and enhanced photovoltaic cell short-circuit currents, fill-factors, and power conversion efficiencies (4.7%) versus the linear NDT isomer.
