Efficient synthesis of mono- and bis-arylated ethylenedioxy thiophene-based functional π-conjugated molecules via clay-supported palladium-catalysed direct arylation reactions

An active Pd catalyst was prepared by the modification of montmorillonite clay. The catalyst was found to be effective for the synthesis of ethylenedioxy thiophene-based π-conjugated molecules. The reaction proceeded through clay-supported Pd-catalysed di

Donor-acceptor dyes with fluorine substituted phenylene spacer for dye-sensitized solar cells

A new series of organic sensitizers LJB-H, LJB-Fo and LJB-F m with triphenylamine, 3,4-ethylenedioxythiophene plus various functionalized phenylenes, and cyanoacrylic acid as the donor, π-spacer, and anchoring group, respectively. These organic sensitizers exhibit much higher molar extinction coefficients than the parent LJ1 dye as well as reveal a remarkable fluorine substituent effect. LJB-Fm with fluoro substitution at the meta position relative to cyanoacrylic acid possesses a lower S0-S1 gap and weaker coupling with the TiO 2 electrode (cf.LJB-H and LJB-Fo). Conversely, due to the resonance effect with respect to cyanoacrylic acid, the ortho-F-substituted LJB-Fo has a larger energy gap but stronger TiO2 affinity. As a result, LJB-Fo shows better DSSC performance with J sc = 15.58 mA cm-2, Voc = 787 mV, FF = 0.67 and η = 8.22%.

Synthesis of mono- and bis-arylated 3,4-(ethylenedioxythiophenes) via direct palladium catalyzed arylation reactions

The synthesis of arylated/heteroarylated 3,4-ethylenedioxythiophene derivatives is reported using a straightforward palladium mediated Heck coupling of 3,4-ethylenedioxythiophene with various aryl/heteroaryl halides.
