Synthesis and Properties of Ethene-Bridged Terthiophenes
摘要:
A method for the facile synthesis of ethene-bridged terthiophenes (EBTTs) in two steps has been developed. The first step is a double Sonogashira coupling between 3',4'-dibromo-2,2':5',2 ''-terthiophene and terminal alkynes to give dialkynylated terthiophenes, and the second step is a cyclization reaction to afford EBTTs. The fundamental physical properties of EBTTs were also studied.
A Terthiophene-Containing Alkynylplatinum Terpyridine Pacman Complex: Controllable Folding/Unfolding Modulated by Weak Intermolecular Interactions
摘要:
Folded and unfolded solid-state structures of a bimetallic alkynylplatinum terpyridine complex with a flexible terthiophene linker have been obtained. Weak intermolecular interactions including pi-pi stacking and C-H center dot center dot center dot O and C-H center dot center dot Cl interactions as well as Cl-pi interactions stabilize the folded structure. In solution, folding is studied by electronic absorption spectroscopy and H-1 and NOESY NMR experiments.

The preparation and crystalstructures of 3,3′′-diethynyl-2,2′:5′,2′′-terthiophene (A2T3) and three Au(I) complexes containing this ligand are reported. One of the complexes, Au2(dppm)(A2T3), has a short Au−Au distance (3.1969 Å) because of an aurophilic interaction. UV/vis absorption and emission spectra of the complexes and ligand at 298 and 85 K and photoinduced electron transfer to methyl viologen
