Thermoinduced structural-transformation and thermochromic luminescence in organic manganese chloride crystals†
Abstract
The [Mn2Cl9]5− mode of red emissive (C4NOH10)5Mn2Cl9·C2H5OH under thermal treatment will be cleaved into [MnCl4]2− in the green emissive (C4NOH10)2MnCl4 with the departure of ethanol. The rapid conversion of luminescence from red to green provides new insight into the luminescence origin and thermal stability of organic–inorganic metal halide hybrids.
