摘要：

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.
