Multifunctional characteristics of zero-dimensional hybrid organic manganese chloride perovskites

In recent years, metal halide perovskites have been developed to create materials that are nontoxic and highly luminescent. Tin, copper, germanium, zinc, bismuth, and other lead-free perovskites have been produced the potential applications in optoelectronic devices. Here, the zero-dimensional hybrid inorganic-organic perovskite structure of hexaimidazolium tetrachloromanganate(II) hexachloromanganate(II), (C3H5N2)(6)[MnCl4][MnCl6] or HImMC, with red Mn2+-centered phosphorescence at 660 nm with (t(2g))(3)(e(g))(2) -> (t(2g))(4)(e(g))(1) electronic transition in octahedral geometry and stability under high temperature (similar to 450 K), is reported. The optical band gap of HImMC is about 3.8 eV. Moreover, this 0 D hybrid perovskite exhibit large ferroelectric spontaneous polarization of 3.2 mu C/cm(2) at room temperature. Hence, the newly described member of the 0 D organic-inorganic hybrid perovskite family holds significant promise for optoelectronic devices.
