-
We report the chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or a ligand-free copper catalyst. The reactions by these two types of catalysts proceeded with a high chemoselectivity and afforded monobrominated triarylamines in good yields. These products are useful intermediates for the synthesis of unsymmetrical bistriarylamines.

- Meta versus para substituent effect of organic dyes for sensitized solar cells
-
A series of new metal-free organic donor-bridge-acceptor dyes comprising a triphenylamine moiety as the electron donor, and a cyanoacrylic acid (dye series A) or a carboxylic acid moiety (dye series B) as the electron acceptor were synthesized and utilized for dye-sensitized solar cells (DSSCs). The triphenylamine moiety was linked to the main chromophore through either a para or a meta position across a phenyl group in order to examine the difference of structural effect. Both types of compounds exhibited apparent solvatochromic shift in their fluorescence spectra, showing the ready formation of charge separated states in both the para and meta-isomers. Quantum mechanical calculations were performed by using the density functional theory (DFT) at the B3LYP/6-31G(d,p) level to gain insight into the electron distributions surrounding the para and meta-substituted triphenylamine groups. The movement of an electron from the donor to the acceptor under the irradiation of light can be depicted by the time-dependent DFT (TDDFT) calculations, and the results were compared with experimental observations. These dyes were used effectively as sensitizers in DSSCs after being absorbed on surface of nanocrystalline TiO 2. The incident photo-to-current conversion efficiency (IPCE) spectra of the para isomers are broader than that of the corresponding meta isomers, and the short-circuit current density (Jsc) values of the former is also higher than the latter. Dyes of series A exhibited overall conversion efficiencies of 1.27-4.12%, depending on the relative values of Jsc, under AM 1.5 G irradiation (100 mW cm-2). For dyes of series B, the para isomers showed overall better performance than the meta isomers, i.e., higher values for all three parameters Jsc, Voc (open-circuit voltage), and ff (fill factor), thus led to a higher conversion efficiency.

- 13C NMR Study of ortho-, meta- and para-Substituted Phenylhiphenylamines: Substituent Effect Correlations
-
The 13C chemical shifts of 11 substituted triphenylamines have been determined and the assignment of these resonances made using intensities, 1H and 19F couplings and predictions from bond additivity relationships. 13C chemical shifts at carbons bearing the substituent and at carbons ortho to the substituent correlated reasonably well with the Q parameter.A multiple regression analysis of chemical shifts with the field and resonance parameters of Swain and Lupton and the Q parameter produced significantly better correlations than those obtained when Q was omitted for these positions. 13C chemical shift correlations for carbons meta and para to the substituent were not significantly better than when Q was omitted.Significant correlations were obtained between field and resonance parameters and 13C chemical shifts of C-o and C-p, and C-i, C-o, C-m and C-p of the non-substituent bearing phenyl rings in ortho- and para-substituted phenyldiphenylamines, respectively.
