Abstract:	We present a simple, versatile, and scalable procedure to produce SnS nanostructured layers based on an amine/thiol-based molecular ink. The ratios amine/thiol and Sn/S, and the reaction conditions, are systematically investigated to produce phase-pure SnS planar and conformal layers with a tremella-like SnS morphology. Such nanostructured layers are characterized by excellent photocurrent densities. The same strategy can be used to produce SnS-graphene composites by simply introducing graphene oxide (GO) into the initial solution. Conveniently, the solvent mixture is able to simultaneously dissolve the Sn and Se powders and reduce the GO. Furthermore, SnSSe ternary coatings and phase-pure SnSe can be easily produced by simply incorporating proper amounts of Se into the initial ink formulation. Finally, the potential of this precursor ink to produce gram-scale amounts of unsupported SnS is investigated. _.
