Photochemistry of Flavonoids [PDF]

Molecules, 2010
Flavonoids and their photochemical transformations play an important role in biological processes in nature. Synthetic photochemistry allows access to molecules that cannot be obtained via more conventional methods. This review covers all published synthetic photochemical transformations of the different classes of flavonoids. It is first comprehensive

Room temperature exciton–polariton Bose–Einstein condensation in organic single-crystal microribbon cavities

Nature Communications, 2021
The use of room temperature exciton–polariton Bose–Einstein condensation is limited by the need for external high-finesse microcavities. The authors generate room temperature EPs with single-crystal microribbons as waveguide Fabry–Pérot microcavities ...
