Synthesis, Crystal Structure and Recognition Properties of a New Benzothiazole Derivative: C28H24N4O2S

摘要

A benzothiazole-based compound 1,C28H24N4O2S,has been synthesized and characterized by single-crystal X-ray diffraction.It crystallizes in monoclinic,space group P21/c with a =9.6309(14),b =15.230(2),c =17.197(3) (A),β=105.222(2)°,V=2433.9(6) (A)3,Z =4,F(000) =1008,Dc =1.311 Mg/m3,Mr =480.57,μ =0.166 mm-1,the final R =0.0509 and wR =0.1481 for 6643 observed reflections with I ＞ 2σ(I).The crystal structure of compound 1 is stabilized by C-H…O,N-H…N,N-H…O,O-H……N and C-H…N hydrogen bonds.The spectroscopic studies of the title compound toward various metal ions were also investigated in 25％ (V/V) ethanol aqueous solution,and the result showed that it can selectively recognize Cu2+ with fluorescence quenching.
