Formation of PbBr-Based Layered Perovskite Structure Having Poly(thiophene) as an Organic Layer by Soaking Thin Film of Hydrogen Bromide Salt of Poly(3-aminododecylthiophene) in Aqueous Lead Bromide Solution

When a spin-coated film of hydrogen bromide salt of poly(3-aminododecylthiophene), PC12T·HBr, was soaked in an aqueous solution of PbBr2, PbBr-based layered perovskite structure combined with a semiconductor layer of two-dimensional sheets of PbBr6 octahedra and an organic semiconductor layer of poly(thiophene) was formed.
