Resumo(s)
Over the last two decades, investigations in the field of conjugated polymers (CPs) have attracted significant attention due to their unique optical and electrochemical properties, in particular, their application in sensing devices. Sensory signal amplification (compared to small-molecules), versatile structures that can be easily adapted to adjust solubility, are some of the features that have made CPs fluorescence sensory platform of choice in the recente years. The incorporation of calixarenes, a class of synthetic molecular receptors possessing intramolecular cavities capable of selectively interact and establish specific host-guest complexes with neutral and ionic molecular guests in solution and solid-state, in CPs allows the construction of systems with enhance sensitive and selective capabilities towards explosives, contaminants, and biological materials.
In this communication we report the results of the chemosensing ability of newly designed bicyclic calix[4]arene-carbazole-polymers (Calix-OCP-PPE-CBZs) with distinguished carbazole linkages in the polymer main chain, towards the detection of explosives (nitroaromatic compounds (NACs) and nitroaliphatic compounds) and nitroanilines (Nas) in liquide phase.
