title: Thiazole as a weak electron-donor unit to lower the frontier orbital energy levels of donor-acceptor alternating conjugated materials.
abstract: We demonstrate that the substitution of the thiophene by the thiazole heterocyclic compound as a weak electron-donor unit, in donor-acceptor alternating conjugated materials, allows a simultaneous downshift of both HOMO and LUMO levels while keeping the energy bandgap almost unchanged.
