Macromolecular Symposia. ISSN.1022-1360. Vol. 352, N.º 1, SI(2015), pp. 87-941022-13601521-3900http://hdl.handle.net/10400.21/5815New homoditopic bis-calix[4]arene-carbazole conjugates, armed with hydrophilic carboxylic acid functions at their lower rims, are disclosed. Evidence for their self-association in solution was gathered from solvatochromic and thermochromic studies, as well as from gel-permeation chromatography analysis. Their ability to function as highly sensitive sensors toward polar electron-deficient aromatic compounds is demonstrated.engCalix[4]arenesFluorescence sensorsSelf-assemblingSupramolecular polymersjournal article10.1002/masy.201400166
