About
Stable, Earth Abundant, Redox-Active, Homogenous Photocatalysts Tech ID: UA19-181 Invention: This invention opens a new class of homogeneous photocatalysts. This invention overcomes current system limitations by creating a new class of carbenium-based compounds which are stable and redox active, comprise earth abundant and inexpensive materials, have a tunable design, and are easy to synthesize at moderate to high temperatures. These compounds may also be used as highly fluorescent dyes with large extinction coefficient and long fluorescent lifetimes. Background: Heterogeneous photocatalysts are limited by system constraints, including inefficiencies in energy utilization, turnover, chemical species mass transport, and need for surface area for photon exposure. Homogenous and heterogenous catalysts may require rare and expensive materials. Use of toxic metals may necessitate expensive downstream separations to remove trace impurities. Removing such limitations can reduce costs and enable new chemicals routes, including supporting applications in green chemistry and renewable energy.
