Interaction of Triethylamine with Phenylacetylene and Exciplex Formation Study in Solutions
Dec 2024
Fast Track Article
Journal Title:
Current Physical Chemistry
Phenylacetylene interacts with triethylamine in the excited state. Hence the formation of weak charge transfer binary molecular complex species popularly known as exciplex has been investigated. The exciplex is formed probably due to the interaction of the excited state phenylacetylene dipole and C-H dipole of triethylamine in the non-polar aprotic solvent cyclohexane. Exciplex formation is very much dependent on the concentration of triethylamine. High Read More
