General description

Phosphine is an organophosphorus compound that can be used as a ligand with electronic and steric properties. It can be incorporated into the semiconductor to tune the crystallinity and composition of the nanocrystals by enhancing their photoconductive properties.

Application

Phosphine may be used to modify the n-type single walled carbon nanotubes(SWCNTs) for the development of flexible thermoelectric materials. It may also be used as a catalyst in the preparation of cyclobuteno(60)fullerenes which finds potential applications in n-type organic semiconductor.
Phosphine is used primarily in the manufacture of III-IV semiconductor materials by OMCVD and as a dopant in crystalline and amorphous silicon.
Precursor to III-V semiconductor thin films. Also useful as a dopant for crystalline and amorphous silicon.

Phosphine resistance alleles might be expected to negatively affect energy demanding activities such as walking and flying, because of the inverse relationship between phosphine resistance and respiration. We used an activity monitoring system to quantify walking of Rhyzopertha dominica (F.)...

The phosphine-promoted [3 + 2] cyclizations between γ-substituted allenoates and arylideneoxindoles have been applied to the stereoselective synthesis of spiro(cyclopentene)oxindoles with trisubstituted cyclopentene units. It has been demonstrated that PPh(3) operates a very efficient control of the relative stereochemistry of...
