Co@pyr/APTZCMNPs was synthesized, and some of its characteristic analyses, such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) were investigated. The results indicated that this heterogeneous catalyst was an excellent and reusable system to synthesize of 14H</e...
We found that dibenzo-18-crown-6 (DB18C6) can be used as an ionophore to make a tin (II)-ionselectivemembrane electrode. The electrode exhibits a near Nernstian response for Sn2+ ions over aconcentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27.5 ± 0.6 mV per concentration decadein an acidic solution (pH=1). The limit of detection was 8.0× 10-7 M. It has a response time of < 20s an...
Dibenzo[b,h][1,6]naphthyridines were synthesized in one pot by reacting 2-acetylaminobenzaldehyde with methyl ketones under basic conditions via four sequential condensation reactions. This method was also applied to the synthesis of 1,2-dihydroquinolines. 6-Methyl-1,6-dibenzonaphthyridinium triflates showed strong fluorescence, and the fluorescence intensities were changed upon intercalation i...
