Working Paper
Ali, H., Ahmed, I., Robertson, K., & Lanterna, A. PDI-functionalised glass beads: efficient, metal-free heterogeneous photocatalysts suitable for flow photochemistry

Perylene diimides (PDI) have an extraordinary ability to activate both energy and electron transfer process upon light excitation, however, their extremely low solubility has hindered their wide use as photocatalysts. Here, we show a series of suppor... Read More about PDI-functionalised glass beads: efficient, metal-free heterogeneous photocatalysts suitable for flow photochemistry.
