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 structurally characterized dinuclear platinum( II )–terpyridyl complexes [{Pt( t Bu 3 ‐tpy)} 2 (CC) n ](X) 2 ( 1 – 3 ; t Bu 3 ‐tpy=4,4′,4′′‐tri‐ tert ‐butyl‐2,2′:6′,2′′‐terpyridine) upon increasing the extent of π conjugation of the alkynyl bridge.
