Nano rutile TiO₂catalysed synthesis of (E)-4-(2-(1-(4-chlorophenyl)-1H-phenanthro[9,10-d]imidazol-2-yl)vinyl)-N,N-dimethylaniline and its interaction with super paramagnetic nanoparticles

Abstract

The synthesis of (E)-4-(2-(1-(4-chlorophenyl)-1H-phenanthro[9,10-d]imidazol-2-yl)vinyl)-N,N-dimethylaniline (CPPIVI) has been carried out using TiO 2 (R) as catalyst under solvent free conditions and characterized by NMR spectral studies. The catalyst was characterized by scanning electron microscopy (SEM) and Xray diffractometry (XRD). The catalyst is reusable with satisfactory results. The synthesised phosphated styrylimidazole (PSI) and phosphated styrylimidazole bound magnetic nanoparticles (PSIMN) were characterized using SEM, transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), XRD and Fourier-transform infrared spectroscopy (FT-IR). The intensities of the absorption and emission maxima are of the following order: PSIMN > PSI > CPPIVI. Conductance and VSM measurements were also carried out. The lifetime of the excited states of PSIMN, PSI and CPPIVI has been obtained. A prototropic study of CPPIVI has also been made at different concentrations.
