Organic–inorganic metal halides (OIMHs) have attracted considerable attention owing to their unique optoelectronic properties. Here, we successfully synthesized five lead, manganese and copper containing OIMHs based on 4-aminodiphenylmethane (C 13 H 13 N) and 4,4′-methylenedianiline (C 13 H 14 N 2 ). Among them, (C 13 H 14 N) 2 PbCl 4 and (C 13 H 14 N) 2 PbBr 4, both exhibiting two-dimensional frameworks, crystallize into the Pmm 2 and P 2 1 / c space groups, respectively, and present optical band gaps of approximately 3.6 and 3.0 eV. (C 13 H 14 N) 2 PbCl 4 demonstrates blue light emission centered at 502 nm with a substantial full width at half-maximum (fwhm) of 180 nm and a Stokes shift of 182 nm, originating from self-trapped exciton emission. In contrast, (C 13 H 14 N) 2 PbBr 4 displays blue photoluminescence characterized by a fwhm of 26 nm and an emission peak at 417 nm, corresponding to free exciton emission. Additionally, we investigated three zero-dimensional OIMHs: (C 13 H 14 N) 4 MnCl 6 ·Cl, (C 13 H 15 N 2 ) 4 CuCl 10 ·4H 2 O, and [(C 13 H 16 N 2 )(C 2 H 6 NH 2 )MnCl 4 ·2H 2 O]·Cl. Our research delves into their fundamental optical properties and luminescence mechanisms, providing valuable insights for future studies.
