  Spectroscopic Study of Phosphine-Substituted Oligothiophenes

  摘要：

  The spectroscopic behaviour (solution and solid-state absorption and emission) of a series of mono(diphenylphosphino) and bis-(diphenylphosphino) alpha-substituted oligothiophenes varying in length from one to three thienyl rings is described. The absorption spectra red-shift with increasing oligomer length, and the spectra of the bisphosphines are red-shifted, relative to the monophosphines that contain the same number of thienyl groups. In solution, emission from the mono- and bithienyl compounds is broad and shows a large Stokes shift, attributed to a planar excited state due to the n --> pi* nature of the excitation. Emission from the terthienyl compounds shows a much smaller Stokes shift and is attributed to a thienyl-based pi --> pi* transition. In the solid state, similar effects are observed in both absorption and emission spectra. Density functional theory (DFT) calculations show that the contribution of the P lone pair to the highest occupied molecular orbital (HOMO) diminishes as the oligomer length increases, supporting the experimental results.

  通过钠选择性裂解C-P键从ArCl制备有机膦的方法

  摘要：

  研究了磷化钠R 2 PNa和其他碱金属磷化物R 2 PM（M = Li和K）的制备，应用和反应机理。R 2 PNa可以通过SD（精细分散在矿物油中的钠）与次膦酸酯R 2 POR'和氯膦R 2 PC1的反应准确而选择性地制备。R 2 PNa也可以通过选择性裂解C–P键由三芳基膦和二芳基膦制备。在这些反应中，Na优于Li和K。R 2 PNa与多种ArCl反应以有效产生R 2PAr。ArCl优于ArBr和ArI，因为它们只会降低产品收率。另外，Ph 2 PNa优于Ph 2 PLi和Ph 2 PK，因为Ph 2 PLi不产生与PhCl的偶联产物，而Ph 2 PK仅产生低产率的产物。ArCl苯环上的吸电子基团极大地促进了与R 2 PNa的反应，而烷基降低了反应活性。氯乙烯和烷基氯RC1也有效地反应。当t-BuCl没有产生相应的产物，金刚烷基卤化物可以高产率得到相应的膦。通过这种方法，由相应的氯化物制备了多种膦。还可以方便地从Ph

  The reaction of [Au(tht)Cl] (tht = tetrahydrothiophene) with 2,5-bis(diphenylphophanyl)thiophene (dppthph) and Se(SiMe3)2 leads to the formation of [Au18Se8(dppthph)6]Cl2. This compound crystallizes in two modifications, both containing a cluster dication with nearly identical gold–selenium cores. The dication consists of two subunits only connected by six aurophilic interactions. ESI MS demonstrates

  日期：2005.2.1

  A series of gold(I) complexes containing phosphino(oligothiophene) ligands of varying conjugation length has been prepared. Solid state crystal structures of (PT3)AuCl (PT3 = 5-diphenylphosphino-2,2':5',2"-terthiophene) and AuCl-(PTP)AuCl (PTP = 2,5-diphenylphosphinothiophene) have been obtained. The complex AuCl(PTP)AuCl crystallizes as a dimer with two intermolecular Au-Au contacts. Variable temperature NMR spectroscopy is used to demonstrate the presence of aurophilic interactions in solution for Aul(PTP)Aul. Dual emission is observed for AuCl(PTP)AuCl in solution and is attributed to emission from both monomer and dimer. In the solid state, dimer emission is dominant. The iodo analogue, Aul(PTP)Aul, shows only low energy dimer emission in both solution and the solid state. Compounds in which the ligands contain longer bridges (either bithienyl or terthienyl) show absorption and emission bands due to the pi-pi* transition only, both in solution and the solid state.
