Effect of structural modification on the performances of phenothiazine-dye sensitized solar cells

Three novel dyes DX1, DX2 and DX3 containing phenothiazine are designed and synthesized for dye-sensitized solar cells (DSSCs). Photophysical, electrochemical and photovoltaic properties of the three dyes have been systematically investigated. The results

A METHOD OF CONTROLLING THE BROMINATION OF THIOPHENE DERIVATIVES

Provided is a method for regioselective synthesis of a bromoalkylthiophene with improved yield. A 3-alkylthiophene is activated at -78not;C with n-BuLi for about 1.5 hour and then reacted with bromine to give a bromoalkylthiophene with good regioselectivity:

LiCl-promoted chain growth kumada catalyst-transfer polycondensation of the "reversed" thiophene monomer

The effect of LiCl on the chain growth Kumada catalyst-transfer polycondensation (KCTP) of the "reversed" thiophene monomer, 5-bromo-2-chloromagnesio-3-hexylthiophene (3a) (that has bulky substituent adjacent to the chloromagnesium group), was investigate

A selective and direct synthesis of 2-bromo-4-alkylthiophenes: Convenient and straightforward approaches for the synthesis of head-to-tail (HT) and tail-to-tail (TT) dihexyl-2,2′-bithiophenes

A straightforward method for the synthesis of 2-bromo-4-alkylthiophenes was developed, and the desired products were obtained in the highest chemical yields (>90%) reported to date. 2-Bromo-4-alkylthiophenes were synthesized by regioselective lithiating of 3-alkylthiophenes with n-BuLi and quenching with bromine at -78°C. Moreover, a simple and efficient protocol for the synthesis of dihexyl-2,2′-bithiophenes was developed by employing 2-bromo-4-hexylthiophene instead of the commonly used monomer, 2-bromo-3-hexylthiophene. Kumada and Suzuki cross-coupling reactions were conducted to synthesize the desired products as head-to-tail (HT) and tail-to-tail (TT) regioisomers in high yields and excellent selectivity.

The reactivity of some 5-bromo-2-nitro-3-R-thiophens (Ia-g; R=H, Me, Et, Prn, n-hexyl, Pri, and But), 3,4-dibromo-2-nitro-5-R-thiophens (IIa and b; R=H and Me), 3-bromo-2-nitro-5-R-thiophens (IIIa and b; R=H and Me), and 2-bromo-3-nitro-5-R-thiophens (IVa and b; R=H and Me) with amines and sodium benzenethiolate has been studied in methanol at various temperatures.Piperidinodebromination of compounds (Ia and c) has also been studied in benzene, in dioxan, and in dioxan-water (60:40 and 10:90).Independent of the position of the alkyl group (meta or para with respect to the leaving bromine), an unexpected alkyl activation has been observed, which represents a further exception to the electron-releasing behaviour of alkyl groups.
