Abstract A new cadmium coordination polymer [Cd(DPFE)(adip) 0.5 (NO 3 )] n ( 1 ) has been synthesized hydrothermally from the self-assembly of the Cd 2+ ion with a new π-conjugated rigid ligand DPFE and the adipic acid, where DPFE = 2,7-di(pyridin-4-yl)-9 H -fluorene and H 2 adip = adipic acid. The structure of 1 was full characterized by elemental analysis, FT-IR spectroscopy and single crystal X-ray
摘要 通过 Cd 2+ 离子与新型 π 共轭刚性配体 DPFE 的自组装,水热合成了一种新的镉配位聚合物 [Cd(DPFE)(adip) 0.5 (NO 3 )] n ( 1 )己二酸,其中 DPFE = 2,7-di(pyridin-4-yl)-9 H-芴和 H 2 己二酸 = 己二酸。通过元素分析、FT-IR光谱和单晶X射线衍射对1的结构进行了全面表征。结构分析表明化合物1是一个基于双核Cd(II)的二维(4,4)层,吡啶环和苯环之间存在两种强分子内π-π堆积相互作用。此外,还研究了热重分析和固态发光特性。
