The materials were obtained by reaction of a tetraaminocalix[4]arene derivative with three aldehydes as mesogenic promotor moieties: 4-(4’- decyloxybenzoyloxy)benzaldehyde (A), 4-(4’-decyloxybenzoy- loxy)salicylaldehyde (B) and 4-(3’,4’-didecyloxybenzoyloxy)sali-cylaldehyde (C). All of the compounds exhibit liquid crystalline properties and these were studied by optical microscopy, DSC and X-ray diffraction. The relationship between the structure and the mesomorphic behavior of the compounds is discussed. The binding recognition and selectivity towards cations have been studied by absorption and fluorescence spectroscopy2017http://zaguan.unizar.es/record/13206210.1002/slct.201601826http://zaguan.unizar.es/record/132062oai:zaguan.unizar.es:132062info:eu-repo/grantAgreement/ES/DGA/E04info:eu-repo/grantAgreement/ES/DGA/E39info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-52331-Rinfo:eu-repo/grantAgreement/ES/MINECO/CTQ2015-70174-PChemistrySelect 2, 1 (2017), 101-109All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
