文摘Under hydrothermal conditions,homochiral ligand(4aR,8aR)-2,3-di(thiophen-2-yl)-decahydroquinoxaline (DTDCQ) reacted with CuBr to give 1D helical chain complexes[(DTHHQ)CuBr]_n(1).Single crystal X-ray determination shows that compound 1 crystallize in chiral space groups P2_12_12_1 and the experimental result indicated that 1 has SHG(second harmonic generation) active with approximate responses 0.4 times that of urea,Fluorescent analysis showed it exhibits one intense emission band at 377 nm when the exciting radiation was set at 340 nm. Dielectric constant of compound 1 were measured at different frequencies at room temperature.
