Popis:	Previous work has shown that nanoscale lamellar inorganic–organic hybrid materials can be synthesized on transparent conductive substrates via the electrodeposition of Zn(OH)2 in the presence of conjugated surfactants. These surfactants introduce p-type semiconducting supramolecular phases; thus, following conversion of the Zn(OH)2 phase to the n-type semiconductor ZnO, the lamellar hybrids exhibit high photoconductive gains and can exhibit photovoltaic activity. We report here on a family of carboxylated terthiophene-based surfactants designed with systematic modifications to molecular geometry, valency, and flexibility to investigate how these features affect the synthesis of the p-type/n-type semiconducting hybrid materials. We use scanning electron microscopy (SEM) and two-dimensional (2D) grazing-incidence X-ray diffraction (2D-GIXD) to correlate molecular features of the surfactants with growth and orientation of the nanoscale lamellae that form during electrodeposition on either hydrophilic or hydr...
