Exploiting modularity in template-controlled synthesis: A new linear template to direct reactivity within discrete hydrogen-bonded molecular assemblies in the solid state

Abstract

Co-crystallization of 1,8-naphthalenedicarboxylic acid (1,8-nap) with trans-1,2-bis(n-pyridyl)ethylene (n, n’-bpe) (n = 2 or 4) yields a discrete four-component molecular assembly, 2(n, n’-bpe)·2(1,8-nap)1, that is held together by four O-H⋯N hydrogen bonds where the dicarboxylic acid, serving as a linear template, directs alignment of olefins in the solid state for [2 + 2] photoreaction. © 2001 The Royal Society of Chemistry.
