A series of phosphorescent Au(I) bis(N-heterocyclic allenylidene) complexes, namely [Au(=C=C=CR1R2)2]+X-, were synthesized and structurally characterized. These organometallic complexes exhibit panchromatic transient absorption upon electronic photo-excitation and can self-organize into lyotropic...
合成了一系列磷光的Au(I)双(N-杂环烯基)络合物,即[Au(= C = C = CR1R2)2] + X-,并对其结构进行了表征。这些有机金属配合物在电子光激发下表现出全色瞬态吸收,并能自组织成溶致...

Bis(N-methylimidazole-2-yl)butadiyne (bmib) has been prepared starting from N-methylimidazole following two different pathways. Bmib fluoresces and is capable of forming 1D coordination polymers by clamping together metal units. The molecular structure of a zinc coordination polymer based on bmib and zinc acetate resembles a battlement of a fortress.

Novel imidazolylethynyl-zinc-porphyrin 1a and its meso,meso-linked bisporphyrin 5M were synthesized effectively by the reaction of the corresponding bromoporphyrins and 2-imidazolylethyne in the presence of palladium-arsenic catalyst. The complementary coordination of monomer 1a into dimer 2a was observed by H-1 NMR and UV-Vis spectroscopy. Self-association constant of 1a to 2a in CHCl3 (including 0.5% ethanol) was determined as 1.84 x 10(7) M-1 by UV-Vis titration of 2a with N-methylimidazole. UV-Vis absorption and fluorescence spectra of la, 2a, monomer 5M, and its polymer 5P were compared. (c) 2006 Elsevier B.V. All rights reserved.
