A Cobalt-Containing Polysilane as an Effective Solid-State Catalyst for the Hydrosilylation of Alkenes

open access: yes, 2023
A cobalt-containing polysilane was readily obtained from the treatment of poly(monohydro)silane with Co2(CO)8 at 60 °C. The resulting polysilane-supported cobalt catalyst (Co/Si catalyst) acts as a solid-state catalyst that exhibits good catalytic ...

Vinyl-substituted Polysilanes [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1966
Abstract 1-Vinylheptamethyltrisilane, 2-vinylheptamethyltrisilane and vinylpentamethyldisilane have been prepared from the corresponding chlorosilanes and vinylmagnesium chloride. In these compounds, intense absorption maxima were observed in the ultraviolet region, and both the λmax and ε increased with an increase in the chain length ...

Ring Strain‐Promoted Activation of Pyridines by a Saturated BSi2 Cycle

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 1, 2 January 2026.
We report a highly strained boratadisilirane with the elusive anionic BSi2 ring motif. Cleavage of the Si─Si bond during reactions with pyridine derivatives activates them in three different ways: 1) for pyridine itself selective ortho‐CH activation and concomitant hydrogen transfer to a second pyridine molecule occurs, 2) with dimethylaminopyridine ...

In vitro degradation, photo-activated antibacterial activity of sodium copper chlorophyllin crosslinked-polysilane composite coating on magnesium alloys

open access: yesCorrosion Communications
Non-invasive inactivation of bacteria by photodynamic therapy (PDT) and photothermal therapy (PTT) has been recently concerned for biomaterials. A polymethyltrimethoxysilane (PMTMS)-crosslinked sodium copper chlorophyllin (SCC) coating was prepared on ...

A Lewis Base‐Free Trialumane: Enhanced Electrophilicity Based on Consecutive Vacant Orbitals Over Three Aluminum Atoms

open access: yesChemistry – A European Journal, Volume 31, Issue 28, May 19, 2025.
A Lewis base‐free trialumane possessing a 2,4,6‐triisopropylphenyl (Tip) substituent was synthesized by the reaction of alumanyl anion with TipAlBr2. The structure, bonding, and electronic properties of the Tip‐substituted trialumane were analyzed by NMR spectra, scXRD, DFT calculations, XPS, and electrochemical study.

Large Bidirectional Refractive Index Change in Silicon‐rich Nitride via Visible Light Trimming

open access: yesAdvanced Optical Materials, Volume 13, Issue 14, May 16, 2025.
Continuous‐wave visible light trimming of PECVD silicon‐rich nitride micro‐ring resonators enables precise, large bidirectional refractive index tuning. Resonance shifts as fine as 10 pm are achieved with a cost‐effective setup, demonstrating large red shifts of 49.1 nm and blue shifts of 10.6 nm.
