Thus, it is proposed herein to design and synthesize a series of organic photocatalysts PCs based on the cationic azatriangulenium motif for two-photon excited photoredox transformation with CO2 and O2. To reduce the carbon footprint of the chemical industry, much efforts have been paid on studying the promotion of chemical reactions by solar energy.
Photoredox organic transformation was widely explored in the recent decade as an effective means of performing preparative-scale reactions, which are commonly inaccessible via conventional synthetic procedures. In particular, organic transformation occurring via photoactivation of earth-abundant small molecules, e. Related reactions were performed mainly using precious-metal and more recently cheaper organic photocatalysts PCs by single-photon excitation with visible light.
Photon upconversion PUC , via the absorption of multiple photons, were widely explored in optoelectronics, bioimaging and photodynamic therapy. However, two-photon excited photocatalysis was confined mainly to reductive transformation, such as hydrodehalogenation, reductive coupling, hydrogenation and bond-breaking reactions, but related examples in photocatalytic functionalization with small molecules are rare. Photoredox transformation with CO2 and O2 promoted by two-photon excitation will then be examined with visible vis and near infrared NIR radiation.
Detailed mechanistic studies will also be performed. Our website uses cookies to enhance your browsing experience. If you continue to use this website, you consent to our use of cookies. Learn more. Notice: JavaScript is not enabled. Please enable JavaScript to view this site.
