Novel fluorescent anthracene-decorated cyclotri- and cyclotetraphosphazenes (5 and 6) are designed and synthesized, and their chemosensor behaviors against nitroaromatic compounds are examined by UV/Vis and fluorescence spectroscopies for addressing the sensors with cyclophosphazenes for 2,4,6-trinitrotoluene detection. The fluorescence intensities of (5 and 6) are found to be selectively quenched by only 2,4,6-trinitrotoluene through the non-covalent pi center dot center dot center dot pi stacking interactions between anthracene-substituted cyclophosphazenes and 2,4,6-trinitrotoluene. In addition, cyclic voltammetry and theoretical calculation of novel sensor systems are studied. The proposed fluorescent sensor systems are critical in terms of practical detection of 2,4,6-trinitrotoluene. (C) 2019 Elsevier B.V. All rights reserved.
