Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1663-45-2, is researched, SMILESS is P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4, Molecular C26H24P2Journal, Nanoscale Advances called Halogen effects on the electronic and optical properties of Au13 nanoclusters, Author is Gao, Ze-Hua; Dong, Jia; Zhang, Qian-Fan; Wang, Lai-Sheng, the main research direction is gold13 nanocluster halogen effect electronic optical property.Synthetic Route of C26H24P2.
We report an exptl. and theor. investigation of the electronic and optical properties of a series of icosahedral Au13 nanoclusters, protected using different halogen ligands (Cl, Br, and I), as well as 1,2-bis(diphenylphosphino)ethane (dppe) ligands. All three clusters are comprised of the same Au13 kernel with two halogens coordinated to the poles of the icosahedral cluster along with five dppe ligands. UV-vis absorption spectra indicate a systematic red shift from Cl to Br to I, as well as a sudden enhancement of the second excitonic peak for the I-coordinated cluster. D. functional theory (DFT) calculations suggest that all clusters possess a wide HOMO-LUMO energy gap of ~1.79 eV and are used to assign the first two excitonic bands. Frontier orbital analyses reveal several HOMO → LUMO transitions involving halogen-to-metal charge transfers. For the I-coordinated cluster, more complicated I-to-metal charge transfers give rise to different excitation features observed exptl. The current findings show that halogen ligands play important roles in the electronic structures of gold clusters and can be utilized to tune the optical properties of the clusters.
There is still a lot of research devoted to this compound(SMILES：P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4)Synthetic Route of C26H24P2, and with the development of science, more effects of this compound(1663-45-2) can be discovered.
