Synthesis, optical and electrochemical properties of new cyanopyridine derivatives

Add time:08/14/2019    Source:sciencedirect.com

New cyanopyridine derivatives bearing different alkoxy substituents were designed and synthesized to study their optical and electrochemical properties. All the synthesized compounds were characterized using various spectroscopic techniques like IR, NMR, and Mass spectrometry. Their optical and electrochemical properties were explored with the aid of UV–visible spectroscopy, photoluminescence spectroscopy and cyclic voltammetry. Further, these compounds exhibited a very good solubility in organic solvents such as toluene, chloroform, ethyl acetate, THF and DMSO. Therefore, these compounds showed absorption band in the region of 274–355 nm and a blue emission band in the region of 412–438 nm. Finally, their cyclic voltammetry measurements revealed that the energy band gap of the molecules are lies between 1.37 eV and 2.12 eV. As a whole, the obtained preliminary results suggest that these compounds can be used further as optoelectronic materials.
