Partially replacing Pb²⁺ by Mn²⁺ in hybrid metal halide perovskites: Structural and electronic properties

Tailoring the physical properties of hybrid lead metal halide APbX₃ perovskites by means of compositional engineering is one of the key factors contributing to the development of highly efficient and stable perovskite solar cells. While the beneficial effects of partial ionic replacement at the A- and X-sites are largely...

Conjugated poly(azomethine)s via simple one-step polycondensation chemistry: Synthesis, thermal and optoelectronic properties

Three conjugated triphenylamine-based poly(azomethine)s were prepared via well-known polycondensation chemistry using cheap and readily available starting materials and the results were contrasted with rrP3HT. Three functionalized diaminetriphenylamines (TPA(X), X ¼ –H, –OMe, –CN) were polymerized in a simple one-step process with 2,3...
