摘要：

A change in shift! In contrast to the red shift commonly found in organic polyynes and other metal-alkynyl systems, a blue shift in the transition energy was observed in electronic absorption and emission studies on a novel series of structutally characterized dinuclear platinum (II)-terpyridyl complexes [{Pt(tBu3-tpy)} 2-(C≡C)n] (X)2 (1-3;TbU3-TPY = 4,4′,4′-tritert-butyl-2,2':6',2″-terpyridine) upon increasing the extent of π conjugation of the alkynyl bridge.
