Resumen: The synthesis and liquid crystalline behavior of new calixarene Schiff base derivatives are reported. 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 spectroscopy Idioma: Inglés DOI: 10.1002/slct.201601826 Año: 2017 Publicado en: ChemistrySelect 2, 1 (2017), 101-109 ISSN: 2365-6549 Factor impacto JCR: 1.505 (2017) Categ.
