摘要
Three coordination polymers based on the V-shaped 4,4＇-dicarboxybiphenyl sulfone （H2sdba） ligands, [Zn3（μ-OH）2（sdba）2]n·2nH2O 1, [Zn2（sdba）2（4,4＇-bipy）]n·2nH2O 2 and [Zn3（sdba）3（py）2]n·n（py）·nH2O 3 （4,4＇-bipy = 4,4＇-bipydine）, were hydrothermally synthesized and structurally characterized. Complex 1 features the 2D planes constructed by the sdba ligands linking infinite Zn-O-C SBUs. The 4,4＇-bipy ligands in 2 bridge the Zn^II-sdba chains into interpenetrated 2D planes. The 3D network of α-Po topology in 3 is built from tri-nuclear Zn3 units with a [Zn3（OOC）6] structure. The intense blue and yellow luminescence was observed in complexes 1～3 which may result from ligand-to-metal charge transfer （LMCT）.
