- Calix[4]arene-carbazole-containing polymers synthesis, properties and thin films as molecular sensorsPublication . Costa, Alexandra; Barata, Patrícia; Fialho, Carina B.; Prata, José VirgílioCalix[4]arenes, an interesting bow-shaped macrocyles, have been explored due to their valuable properties, e.g. molecular recognition, proving outstanding complexability towards neutral and ionic guests of several origins. In this communication we report the synthesis and the chemosensing ability on the solid state of a new bicyclic calix[4]arene-based polymers integrating phenylene-ethynylene-carbazole units as fluorescente segments (Calix-OCP-PPE-CBZs), in the detection of several nitroanilines (NAs) in vapor phase.
