New complexes based on tridentate bispyrazole ligand for optical gas sensing

▶ Synthesis of 4-[bis[(3,5-dimethyl-1H-pyrazol-1-yl)methyl]-amino]phenol complexes with tranistion metals. ▶ Thin films preparation and optical characterization. ▶ Test in controlled athmosphere as optical gas senging towards SO2, NO2, CO, CH4 and NH3.
