A hydrophobic chain with an azobenzene group incorporated at different positions was click coupled to a maltose polar head by a copper(I)-catalysed azide–alkyne [3 + 2] cycloaddition. The liquid crystalline and gel properties of these azo-amphiphilic materials have been studied. Two of these azo-gelators containing maltose give rise to stable gels in water or in a mixture of water and DMSO at room temperature. The chiral supramolecular assemblies of these gelators have been characterised by NMR, electron microscopy and circular dichroism (CD). The light-response of azo-amphiphiles in supramolecular gels has been studied. Also azo-gels, which contained mixtures of the azo-amphiphilic compounds and a similar structural hydrogelator, have been investigated.2012http://zaguan.unizar.es/record/14978610.1039/c2ra21506chttp://zaguan.unizar.es/record/149786oai:zaguan.unizar.es:149786info:eu-repo/grantAgreement/ES/MINECO/MAT2011-27978-C02-01RSC Advances 2, 30 (2012), 11419-11431All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
