Fluorescent Properties of Manganese Halide Benzothiazole Inorganic-Organic Hybrids.
The reaction of manganese (II) halides MnX2and benzothiazole (btz) in the concentrated acids HX (X = Cl, Br) at 80 °C resulted in the formation of two inorganic-organic hybrid complexes: [(btz)2(MnX4)]·2H2O (X = Cl, 1; X = Br, 2). Both compounds showed green luminescence and exhibited moderate quantum yields of 43.17 % for 1 and 26.18 % for 2, which were directly originated from the tetrahedral coordination of Mn2+ion. Two organic - inorganic hybrids [(btz)2(MnX4)]·2H2O based on MnCl2, benzothiazole and halide acids emitted green light with the moderate quantum efficiencies when excited by 365 nm light.
