Özet

In this study, four pamoic acid esters and a dibenzoxanthene derivative of pamoic acid ester were prepared and characterized by the analytical and spectroscopic methods Molecular structure of the synthesized compounds were determined by single crystal X-ray diffraction studies. Absorpsion and emission behaviours of the compounds were investigated in detail. Fluorescent detection of nitro aromatic compounds [nitro benzen (NB), 4-nitrophenol (4-NP) and 2,4-dinitrophenol(2,4-DNP)] by the synthesized compounds was examined. Sensing cabability to NACs, fluorescent titration experiments were performed and compound (2) exhibit the highest sensitivity against NB with a quenching constant (Ksv) of 1.03 x 10(7) M-1. Finally, non-linear optic properties of the compounds was investiagated by computational (C) 2017 Elsevier B.V. All rights reserved.
