Photoredox/Ti dual-catalyzed dehydroxylative ring-opening Giese reaction of cyclobutanone oximes

open access: yesGreen Synthesis and Catalysis
A dehydroxylative ring-opening Giese reaction of cyclobutanone oximes enabled by photoredox/Ti dual catalysis has been reported in this work. This protocol avoids the prefunctionalization of oximes and the use of stoichiometric triarylphosphine reagents.

Coupled Environmental Effects in Competitive Inhibition of Dynamic Hydrazone Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
Environment Alters Competitive Inhibition of Crosslinks. Ion concentration, pH, and buffer composition govern exchange kinetics and network stability in dynamic benzyl‐hydrazone hydrogels. These factors are particularly important when utilizing small‐molecule competitors for enhanced control over gel mechanics, underscoring the need to control the ...

Highly Efficient and Cytocompatible Panchromatic Photoinitiators for Photopolymerization and High‐Resolution 3D Printing beyond 450 nm

open access: yesSmall, EarlyView.
Phenothiazine photoinitiators P1 and P2 exhibit panchromatic photoinitiation through efficient SET with iodonium salts. P2 enables rapid red‐light polymerization, while both systems perform under sunlight and smartphone light. P1 supports 460 nm DLP 3D printing and shows lower cytotoxicity than TPO, offering safer photoinitiators for high‐precision ...

Polarity‐engineered Sn‐Ti cluster photoresists for sub‐10‐nm high‐resolution lithography

open access: yesSmart Molecules, EarlyView.
Enhancing the polarity of clusters can optimize their patterning performance; inspired by this strategy, we designed polarity‐enhanced Sn‐Ti oxo clusters via ligand engineering. The optimal TS‐3 with exposure‐induced polarity switch achieves 8 nm patterning in lithography and achieves simultaneous improvement in resolution and patterning performance ...
