Abstract Two new copper(I) complexes [Cu( L 1 ) 2 ]PF 6 ( L 1 = 4-diphenylphosphino-1,5-naphthyridine, 1) and [Cu( L 2 ) 2 ]PF 6 ( L 2 = 4-diphenylphosphino-8-methyl-1,5-naphthyridine, 2 ), have been prepared and characterized. In each of them, the coordinate geometry of Cu atom is a distorted square planar configuration with bond distances and angles in the normal range. Moreover, compound 2 features
摘要 两种新的铜(I)配合物 [Cu( L 1 ) 2 ]PF 6 ( L 1 = 4-diphenylphosphino-1,5-naphthyridine, 1) 和 [Cu( L 2 ) 2 ]PF 6 ( L 2 = 4 -diphenylphosphino-8-methyl-1,5-naphthyridine, 2 ), 已被制备和表征。在它们中的每一个中,Cu 原子的坐标几何是一个扭曲的方形平面构型,键距和角度在正常范围内。此外,化合物 2 具有一维锯齿形链,其由金属络合物阳离子和 PF 6 - 阴离子通过氢键相互作用交联。通过循环伏安法 (CV) 估计的 1 – 2 的 HOMO-LUMO 能隙显示的值按 1 > 2 的顺序排列。1 和 2 都显示了 360 到 430 nm 的低能带和室温下固态可用荧光,λ max = 532–541 nm。
