摘要
溶剂热条件下,用3,4',5-联苯三羧酸(biphenyl-3,4',5-tricarboxylic acid,H3bpt)和1,4-bis[2-(4-pyridyl) ethenyl]benzene (bpeb)合成了一种新颖的有机超分子聚合物[(H2bpt)2(H2bpeb)]n。单晶X-射线衍射研究表明,组分H2bpt与H2bpeb通过强氢键构筑了二维的超分子聚合层,进而通过层间强π-π相互作用形成三维超分子结构。结晶样品通过元素分析、热重(TG)、粉末X-ray衍射等进行了表征。370 nm紫外线激发下,化合物的最大荧光发射波长为516 nm;在365 nm紫外光照射下,晶体样品也显绿色,是潜在的绿色荧光材料。
One novel organic supramolecular polymer [(H_2bpt)2(H_2bpeb) ]n( 1) was synthesized from biphenyl-3,4',5-tricarboxylic acid(H_3bpt) and 1,4-bis[2-( 4-pyridyl) ethenyl]benzene( bpeb) under solvothermal conditions.Single-crystal structural analysis revealed that a two-dimensional supramolecular polymeric layer was built from H_2bpt and H_2bpeb through strong hydrogen bonds. The elemental analysis,thermal stability,powder X-ray diffractions,and so on,were carried out. When being excited at 370 nm,compound 1 exhibited emission peak at 516 nm. Under the 365 nm ultraviolet light,the crystal 1 displayed green,which may be used as potential green fluorescent material.
