Synthesis and Electrochemical Properties of Novel 1,3,5-Tris(oligothienyl)benzenes: A New Generation of 3D Reticulating Agents

Electrochemistry and photoelectrochemistry of two donor–acceptor polythiophene polymers with acceptor moieties in the main chain

“…The final product, purified by column chromotagraphy, was a dark orange solid and its 1 The synthesis of BT-azine was a two step process. First, 2,2 0 -bithiophene was acetylated by treating it with n-BuLi in Et 2 O and then adding dimethyl-acetylamide to produce 5-acetyl-2,2 0 -bithiophene as a yellow solid in 41% purified yield [30]. This was then mixed with hydrazine hydrate in a 2:1 ratio in ethanol with 0.5% acetic acid and refluxed overnight.…”

Mono-Ketone Modified C60s for Acceptor Materials in Organic Photovoltaic Cells

“…In addition, we incorporated thiophenyl and bithiophenyl groups to increase the compatibility with conventional donor polymer, such as P3HT. The mono-ketone compounds having thiophenyl group were easily synthesized from the method in the literature [7][8]. Compound 1, 2, 3, and 4 were produced as similar procedure at literature through Hirch-Bingel reaction under mild condition [9][10].…”

“…P3HT [Poly(3-hexylthiophene)] was purchased from Rieke Metals.Synthesis of Mono-ketone Modified Methanofullerene DerivativesGeneral Procedure 2-Hexylthiophene, 2-hexyl-5-5 0 -bithiophene, 1-(thiophen-2-yl)octan-1-one, 1-(2,2 0 -bithiophen-5-yl)octan-1-one, 1-(5-hexylthiophen-2-yl)hexan-1-one, 0 -hexyl-2,2 0 -bithiophen-5-yl)hexan-1-one were synthesized in the similar methods described in the literature[7][8]. Fullerene C 60 (1.0 mmol) was stirred overnight in o-dichlorobenzene solution.…”

Optical Properties and Quantum-Chemical Calculations of Various Bithienyl Derivatives of Benzene, Triazine and Triphenyltriazine as Organic Light Emitting Diodes

“…Thiophenes with well-defined chemical structures have recently attracted great attention not only as an example of model compounds for conducting materials, but also as a new class of functional π-electron systems [5][6][7][8][9][10][11]. Branched oligothiophenes based on central phenyl core have come to the fore over the last several years, acting both as monomers in cross-linked semiconducting polymers [12][13][14][15] and as components of conjugated dendrimers [16][17][18].…”
