Molecular Optical Switches Based on [Ru(OAC)(2MQN)₂NO](H2MQN=2-methyl-8-quinolinol)

Abstract:

Reversible photoisomerization between the cis and trans isomer of [Ru(OAc)(2mqn)2NO] (H2mqn=2-methyl-8-quinolinol) was studied quantitatively, using 1H Nuclear magnetic resonance (NMR) spectra. The kinetic study showed that the photoisomerization from trans to cis isomer was first-order and the rate constant (k) is 0.014 (min-1) at 420 nm, 0.0034 (min-1) at 550 nm, respectively. The main absorption band in UV-Vis region for cis and trans isomer was observed from 300 nm to 550 nm, the electronic structure of these compounds was performed with DFT (Density functional theory) calculation and was discussed based on HOMO–LUMO analyses. The study provide detail information to design advance optoelectronic materials based on nitrosylruthenium(II) complexes.
