In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Bis(4-methylpiperidine-1-carbodithioato)-lead(II) and Bis(4-benzylpiperidine-1-carbodithioato)-lead(II) as Precursors for Lead Sulfide Nano Photocatalysts for the Degradation of Rhodamine B, published in 2021, which mentions a compound: 78-50-2, Name is Tri-n-octylphosphine Oxide, Molecular C24H51OP, Reference of Tri-n-octylphosphine Oxide.
Bis(4-methylpiperidine-1-carbodithioato)-lead(II) and bis(4-benzylpiperidine-1-carbodithioato)-lead(II) were prepared and their mol. structures elucidated using single crystal X-ray crystallog. and spectroscopic techniques. The compounds were used as precursors for the preparation of lead sulfide nano photocatalysts for the degradation of rhodamine B. The single crystal structures of the lead(II) dithiocarbamate complexes show mononuclear lead(II) compounds in which each lead(II) ion coordinates two dithiocarbamato anions in a distorted tetrahedral geometry. The compounds were thermolyzed at 180 °C in hexadecylamine (HDA), octadecylamine (ODA), and trioctylphosphine oxide (TOPO) to prepare HDA, ODA, and TOPO capped lead sulfide (PbS) nanoparticles. Powder X-ray diffraction (pXRD) patterns of the lead sulfide nanoparticles were indexed to the rock cubic salt crystalline phase of lead sulfide. The lead sulfide nanoparticles were used as photocatalysts for the degradation of rhodamine B with ODA-PbS1 achieving photodegradation efficiency of 45.28% after 360 min. The photostability and reusability studies of the as-prepared PbS nanoparticles were studied in four consecutive cycles, showing that the percentage degradation efficiency decreased slightly by about 0.51-1.93%. The results show that the as-prepared PbS nanoparticles are relatively photostable with a slight loss of photodegradation activities as the reusability cycles progress.
The article 《Bis(4-methylpiperidine-1-carbodithioato)-lead(II) and Bis(4-benzylpiperidine-1-carbodithioato)-lead(II) as Precursors for Lead Sulfide Nano Photocatalysts for the Degradation of Rhodamine B》 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
