Photoredox Catalysts Based on N‐(Hexyl)benzothioxanthene‐3,4‐dicarboximide for Photopolymerization and 3D Printing Under Visible Light

open access: yesAngewandte Chemie, EarlyView.
In this work, two benzothioxanthene imide dyes demonstrate excellent photochemical properties. When used as photocatalysts, they work with amine and iodonium salt or sulfonium salt to form different three‐component systems for effectively initiating photopolymerization under visible light, through photoredox catalysis processes.

Manipulating Charge Dynamics in Carbon Nitride by Carbon Dot Doping for Efficient Photocatalysis

open access: yesAdvanced Science, EarlyView.
A series of carbon dot (CD) doped graphitic carbon nitride (g‐C3N4) materials have been rationally synthesized, which exhibited different photophysical properties, excitonic behaviors, and photocatalytic degradation activities. It provides valuable insights to deepen the understanding of exciton dynamics based on g‐C3N4 materials, and rational design ...
