摘要：
(Figure Presented) Well organized! A new class of phosphorescent materials was obtained by the coupling of trialkylgallate-functionalized alkynes to a planar PtII terpyridine unit. Pt⋯Pt interactions in these complexes lead to the formation of highly colored organogels and columnar liquid crystals (see picture). Amide groups linking the gallate and alkyne units provide additional stabilization of the structures through hydrogen bonding. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
