Synthesis and Luminescent Behavior of Lead, Manganese, and Copper Containing Organic–Inorganic Metal Halides
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<sub>13</sub>H<sub>13</sub>N) and 4,4'-methylenedianiline (C<sub>13</sub>H<sub>14</sub>N<sub>2</sub>). Among them, (C<sub>13</sub>H<sub>14</sub>N)<sub>2</sub>PbCl<sub>4</sub> and (C<sub>13</sub>H<sub>14</sub>N)<sub>2</sub>PbBr<sub>4</sub>, both exhibiting two-dimensional frameworks, crystallize into the <i>Pmm</i>2 and <i>P</i>2<sub>1</sub>/<i>c</i> space groups, respectively, and present optical band gaps of approximately 3.6 and 3.0 eV. (C<sub>13</sub>H<sub>14</sub>N)<sub>2</sub>PbCl<sub>4</sub> 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<sub>13</sub>H<sub>14</sub>N)<sub>2</sub>PbBr<sub>4</sub> 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<sub>13</sub>H<sub>14</sub>N)<sub>4</sub>MnCl<sub>6</sub>·Cl, (C<sub>13</sub>H<sub>15</sub>N<sub>2</sub>)<sub>4</sub>CuCl<sub>10</sub>·4H<sub>2</sub>O, and [(C<sub>13</sub>H<sub>16</sub>N<sub>2</sub>)(C<sub>2</sub>H<sub>6</sub>NH<sub>2</sub>)MnCl<sub>4</sub>·2H<sub>2</sub>O]·Cl. Our research delves into their fundamental optical properties and luminescence mechanisms, providing valuable insights for future studies.
