Reproducible phenazine molecular stacks

Abstract

Single crystal X-ray diffraction analyses of the 2 : 1 complexes of phenazine with hydroquinone and 1,5-dihydroxynaphthalene and the 3 : 1 complex of phenazine with 4,4'-dihydroxybiphenyl have been performed. It is shown that in these complexes and also in the 3 : 1 complex of phenazine with 5,10-dihydrophenazine, phenazine forms a host framework consisting of one-dimensional channels. The variation of guest molecules and attendant variations in the hydrogen bond patterns, and the reproducibility of phenazine molecular stacks are described
