Fluorescent Properties of Manganese Halide Benzothiazole Inorganic-Organic Hybrids.

Abstract

The reaction of manganese (II) halides MnX2 and 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 365nm light.
