Aplicación

Triphenylphosphine oxide can be used:
  • As a catalyst in Appel-type chlorination reaction of acyclic primary and secondary alcohols.
  • As a catalyst in stereoselective poly and dibromination of α,β-unsaturated esters and β,γ-unsaturated α-ketoester compounds.
  • As a promotor in the diastereoselective synthesis of α-ribofuranosides through ribofuranosylation of alcohols with ribofuranosyl iodides.

Reduced-dimensional perovskites are attractive light-emitting materials due to their efficient luminescence, color purity, tunable bandgap, and structural diversity. A major limitation in perovskite light-emitting diodes is their limited operational stability. Here we demonstrate that rapid photodegradation arises from edge-initiated photooxidation...

Metal halide perovskites have emerged as promising candidates for solution-processed blue light-emitting diodes (LEDs). However, halide phase segregation - and the resultant spectral shift - at LED operating voltages hinders their application. Here we report true-blue LEDs employing quasi-two-dimensional cesium...

A versatile procedure has been developed and validated for the determination of triphenylphosphine oxide (TPPO) at low levels in various active pharmaceutical ingredients (APIs). This procedure incorporates the use of the novel hollow-fiber liquid-phase microextraction (LPME) for the measurement of...
