Small molecule organic material, tris(4-(1-phenyl-1H-benzo[d]imidazole)phenyl)phosphine oxide (TIPO) was newly synthesised and introduced into an n-type interlayer in planar perovskite solar cells for effective electron transport.
Six centrosymmetric mononuclear Eu3+ and Tb3+ complexes of the type [LnL2(hfac)3] have been synthesized employing diphenyl(pyridin-2-yl)phosphine oxide (Ph2P(O)Py), diphenyl(pyridimin-2-yl)phosphine oxide (Ph2P(O)Pym), and diphenyl(pyrazin-2-yl)phosphine oxide (Ph2P(O)Pyr) as supporting ligands (L).
