Abstract

Abstract : Eight 1-D anion coordination polymers (ACPs) based on tricopper complexes including linear, single-stranded helical, and meso -helical polymeric architectures were reported. Abstract : With the idea of supramolecular hosts encircling monoanions, a series of urea-containing trinuclear cationic copper complexes were designed, prepared and structurally analyzed. Copper(i ) acetylides [Cu3 (μ-dppm)3 (μ3 -η 1 -CCC6 H4 -4-NHC(O)NHC6 H4 -4-R)2 ] + (dppm = bis(diphenylphosphino)methane; R = NO2 (1 ), CF3 (2 ), Cl (3 ), H (4 ), t Bu (5 ), and OCH3 (6 )) were prepared with F −, BF4 −, or NO3 − present as the anion. Eight 1-D anion coordination polymers (ACPs), 1 ·F, 2 ·F, 3 ·BF 4, 4 ·F, 5 ·F, 5 ·BF 4, 5 ·NO 3 and6 ·0.5F ·0.5BF 4, were clearly determined by X-ray diffraction. Diversity in the polymeric architecture is generated by both the choice of R-group used and anion present.2 ·F, 3 ·BF 4, 4 ·F, and5 ·F show linear 1-D structures;5 ·BF 4 and5 ·NO 3 feature single-stranded helical structures;1 ·F and6 ·0.5F ·0.5BF 4 exhibit meso -helical structures. Solid state UV-vis absorption and luminescence properties are also discussed.
