Preparation of extended di(4-pyridyl)thiophene oligomers

Electrochemical and Photovoltaic Properties of Electropolymerized Poly(thienylsilole)s

“…16,17 Mono bromobithiophene and monobromoterthiophene were prepared according to the literature. [18][19][20][21] 2,2-Bithiophene (BT) (Aldrich) was purified through vacuum sublimation. The supporting electrolyte for electrochemical measurements was tetrabutylammonium hexafluorophosphate, Bu 4 NPF 6 (SigmaAldrich, 98 % purity, reagent grade), which was stored in a vacuum dessicator over silica gel.…”

New emissive fac-tricarbonylchlorobis(ligand)rhenium(I) complexes prepared from pyridine/thiophene hybrid ligands

“…Thiophene and its derivatives are of current interest due to their potential uses in molecular electronics including nonlinear optics, energy storage, electrochromic devices and electrochemical sensors [6]. An array of thiophene/pyridine hybrid compounds have been prepared [7][8][9][10][11][12][13][14][15] for uses as optical switches [8], non-linear optics [9], fluorophores [12], and several have been bound to metals such as copper [14], rhenium [8], ruthenium [11], and tungsten [8]. One derivative of thiophene that is of particular interest is 3,4-ethylenedioxythiophene (EDOT), which exhibits increased solubility and lower oxidation potentials than thiophene.…”

“…Compounds tributyl-(2,3-dihydro-thieno [3,4-b][1,4]-dioxin-5-yl)-stannane [19], 4-thiophen-2-yl-pyridine [10], 4-[2,2 0 ]bithiophenyl-5-yl-pyridine [10], and 4-bromopyridine [9] were prepared using procedures reported in the literature. All other compounds were purchased from commercial sources and used as received.…”

Sulfur‐Containing Oligomers

“…Oxidative homo-coupling of lithiated bithiophene 402 with CuC12 gave the disubstituted quaterthiophene 403 in a moderate yield (27%). Following hydride Albers et al synthesized a series of (4-pyridyl)-'capped' oligothiophenes [264]. Thus.…”
