摘要：
A D-A type organic luminogen single crystal (CIE-C) and its two Zn.II) complexes [Zn.CIE-P)(C4H4N2) center dot CH3OH] (1) and [Zn.CIE-P).4,4'-bipy)center dot 1.5CH(3)OH] (2) (CIE-P = 2,3-bis.2,4-dihydroxybenzylideneamino)maleonitrile, C4H4N2 = pyrazine, 4,4'-bipy = 4,4'-bipyridine) have been synthesised and studied. The single crystal X-ray diffraction analysis showed that the molecular structure of CIE-C is well planar and the good co-planarity is maintained in the 2D structure; 1 and 2 are all mononuclear complexes. The photoluminescence properties of CIE-C and its Zn.II) complexes have been investigated in the solid state and solution. The novel crystallization-induced emission-enhancement (CIEE) behavior of CIE-C and unusual fluorescence selectivity for THF of 1 and 2 were found.
