Two‐Orders‐of‐Magnitude Enhancement of Photoinitiation Activity via a Simple Surface Engineering of Metal Nanoclusters

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(23)

Published: March 26, 2024

Abstract Development of high‐performance photoinitiator is the key to enhance printing speed, structure resolution and product quality in 3D laser printing. Here, improve efficiency nanoprinting, we investigate underlying photochemistry gold silver nanocluster initiators under multiphoton excitation. Experimental results DFT calculations reveal high cleavage probability surface S−C bonds nanoclusters which generate multiple radicals. Based on this understanding, design several alkyl‐thiolated achieve a more than two‐orders‐of‐magnitude enhancement photoinitiation activity, as well significant improvement fabrication window. Overall, work for first time unveils detailed radical formation pathways activation substantially improves their sensitivity via engineering, pushes limit lithography.

Unusual Regioselective C–H Difluoroalkylation of Heteroarenes under Photoredox Catalysis

Organic Letters, Journal Year: 2024, Volume and Issue: 26(24), P. 5098 - 5104

Published: June 7, 2024

We disclose a new general strategy for the site-selective difluoroalkylation of nonprefunctionalized heteroarenes, such as quinoxaline at C-8 position, and benzothiadiazole, benzoxadiazole, benzothiazole C-4 position via consecutive organophotoredox-catalyzed radical–radical cross-coupling base-assisted hydrogen abstraction reactions. The current methodology represents direct difluoroalkylative to allow broad functional group tolerance wide substrate scope in good excellent yields. Careful experimental investigations detailed DFT calculations revealed exact site-selectivity heteroarenes possible mechanistic pathway.
