Conformationally stressed phthalocyanines: the non-planarity of the 1,4,8,11,15,18,22,25-octaisopentyl derivative
Abstract
An X-ray crystal structure determination reveals that 1,4,8,11,15,18,22,25-octaisopentylphthalocyanine adopts a saddle conformation, a geometry which shows modified spectroscopic properties and reduced photostability relative to planar ring structures.
