Abstract: Abstract Based on 1,2,4,5-benzenetetracarboxylic acid (H4BTEC) and different viologen cations (MQ+ = 1-methyl-4,4′-bipyridinium cation; MV2+ = 1,1′-bis(methyl)-4,4′-bipyridinium dication; EV2+ = 1,1′-bis(ethyl)-4,4′-bipyridinium dication), three novel supramolecular assemblies [(H3O)(MQ)(H4BTEC)(H2BTEC)]·H2O (1), (H3O)(MV)0.5(BTEC)0.5 (2), (H3O)(EV)0.5(H2BTEC) (3), have been synthesized and structurally characterized with viologen cations… read more here.
