Article Synopsis

The study focuses on enhancing silicon-based sol-gel chemistry using photoprotected R-alkoxysilanes to create innovative silicon materials.
Researchers investigated various aspects of synthesis, characterization, and light-triggered reactions using special photoremovable protecting groups (PPGs).
The findings show successful photodeprotection and conversion of silanes into silanols, leading to polymer formation and potential applications in photolithography as light-controlled surface modifiers.

Octa(dimethylsiloxy)silica cages (QM) undergo rapid self-polymerization in the presence of a fluoride catalyst to form complex 3D porous structural network materials with specific surface areas up to 650 m g. This establishes a new method to form bio-derived high inorganic content soft silicas with potential applications in filtration, carbon capture, catalysis, or hydrogen source.
