Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Ceramics International called Nucleation and growth mechanism of wurtzite copper indium disulfide nanoparticles during solution processing, Author is Pradeepkumar, Maurya Sandeep; Singh, Ankit; Basu, Joysurya; Ahmad, Imteyaz Md., which mentions a compound: 78-50-2, SMILESS is CCCCCCCCP(CCCCCCCC)(CCCCCCCC)=O, Molecular C24H51OP, Reference of Tri-n-octylphosphine Oxide.
Synthesis of Cu-In-S (CIS) nanoparticles by hot injection method using a mixed solution of Cu(acac), In(acac) and DDT in solvents OAm and trioctylphosphine oxide (TOPO), was carried in nitrogen atm. Phase and crystallog. structure evolution were evaluated by extracting samples at intermediate synthesis stages and was characterized by X-ray diffraction and transmission electron microscopy. Ex-situ observation of phases indicated the formation and growth of Cu2S at the earlier stages. With further increase in temperature, CIS formed with the diffusion of In3+ ion. Wurtzite CIS nanoparticles preferentially grew along a length (from ∼42 to 62 nm) while the width nearly remained constant to about ∼32 nm. The preferential growth took place along [0002] while the particle width was oriented along [1010], which resulted in nearly oval-shaped nanoparticles. FTIR spectra recorded at different stages of synthesis (50-310°C) pointed towards the ligand exchange mechanism after the addition of sulfur source at (160°C).
The article 《Nucleation and growth mechanism of wurtzite copper indium disulfide nanoparticles during solution processing》 also mentions many details about this compound(78-50-2)Reference of Tri-n-octylphosphine Oxide, you can pay attention to it, because details determine success or failure
