Quinoline-Benzimidazole Conjugate Based Fluorescent Chemosensor: A Ratiometric Sensor for the Differentiation of Rutile and Anatase TiO2 Nanoparticles| Chapter 2 | New Innovations in Chemistry and Biochemistry Vol.7

 The quinoline-benzimidazole conjugate 1 was produced and analysed using standard spectroscopic and analytical techniques. As a possible fluorescent chemosensor, the probe is used to distinguish TiO2 anatase and rutile nanoparticles using the spectrofluorimetry technique. Probe 1 has a photoinduced electron transfer (PET) mechanism for selective TiO2 sensing and a ratiometric sensing response via an intramolecular charge transfer (ICT) mechanism for ratiometric sensing. Fluorescence titration data of TiO2 rutile and anatase phases with conjugate 1 were used to arrive at a 1:2 binding ratio, and the association constants (Ka) of 1+TiO2 anatase and 1+TiO2 rutile were calculated to be 6.34 104 M-2 and 5.179 104 M-2, respectively. Probe 1 had a detection limit of micro molar concentrations of TiO2 nanoparticles. Time and pH effects were also recorded. As a result, the probe 1 might be used on environmental and biological materials.
