Linear assembly of lead bromide-based nanoparticles inside lead() polymers prepared by mixing the precursors of both the nanoparticle and the polymer

Mixing precursors of lead( ii ) polymers with those of lead bromide-based nanoparticles (CH 3 NH 3 PbBr 3 perovskites or PbBr 2 ), at room temperature and in the presence of cyclohexanemethylammonium bromide, generated colloidal nanocomposites which, when deposited on a hydrophobic surface led to long, one-dimensional, ordered and well-defined architectures. Preparation of 1D assemblies of lead halide-based nanoparticles inside a lead bromide polymer by concurrent formation of lead( ii ) oligomers and the nanoparticles in the presence of cyclohexanemethylammonium bromide.
