A polymeric scaffold having pendant alkyne groups was prepared by atom transfer radical polymerization (ATRP) and postfunctionalized by copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) using homo- and heterobifunctional azides. The azides are derivatives of 2,2-bis(hydroxymethyl)propanoic acid (bis-MPA) containing photoresponsive azobenzene and/or liquid crystalline biphenyl moieties. The approach is a convenient alternative to increase the density of functional units in side-chain polymers having moderate polymerization degrees and to modulate the properties of the final material. The article describes the synthesis, characterization, and liquid crystalline properties of the obtained polymers. The effect of the chemical structure and the possible cooperative effects between functional units in the photo-induction of chirality are also evaluated. A switchable photo-transference of chirality from the circularly polarized light (CPL) to material has been achieved. 000149799 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000149799 590__ $$a3.543$$b2012 000149799 591__ $$aPOLYMER SCIENCE$$b12 / 82 = 0.146$$c2012$$dQ1$$eT1 000149799 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000149799 700__ $$aRebolé, J. 000149799 700__ $$0(orcid)0000-0003-2379-8628$$aCustardoy, L. 000149799 700__ $$aGimeno, N. 000149799 700__ $$0(orcid)0000-0002-0922-5615$$aOriol, L.$$uUniversidad de Zaragoza 000149799 700__ $$0(orcid)0000-0003-1141-5933$$aTejedor, R.M.$$uUniversidad de Zaragoza 000149799 700__ $$0(orcid)0000-0001-5556-2172$$aPiñol, M.$$uUniversidad de Zaragoza 000149799 7102_ $$12013$$2765$$aUniversidad de Zaragoza$$bDpto.
