Synthesis and photophysical properties of novel benzophospholo[3,2-b]indole derivatives
Beilstein Journal of Organic Chemistry, 2017 The parent benzophospholo[3,2-b]indole was prepared by the reaction of dichlorophenylphosphine with a dilithium intermediate, which was prepared in two steps from 2-ethynyl-N,N-dimethylaniline.

Stereoelectronic effects on the binding of neutral Lewis bases to CdSe nanocrystals [PDF]
, 2018 Using P-31 nuclear magnetic resonance (NMR) spectroscopy, we monitor the competition between tri-nbutylphosphine (Bu3P) and various amine and phosphine ligands for the surface of chloride terminated CdSe nanocrystals.

Biphenylic Bisphosphines through ortho-Metalation of Aryldiphenylphosphine Oxides
CHIMIA, 1996 Diphenyl-(2-trifluoromethyl)phosphine oxide was metalated next to the diphenylphosphinoyl group with LITMP. Upon iodination and Ullmann coupling, the corresponding 3,3?-disubstituted bis(phosphine oxide) was obtained. When phenyllithium was used

Catalyst-free photooxidation of triarylphosphines under aerobic conditions
Journal of Saudi Chemical Society, 2015 A new method for the photooxidation of triarylphosphines into the corresponding oxides is developed. In this new protocol, neither a catalyst nor an additive is required. The greenest oxidant, oxygen in air atmosphere, is used.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...
