Palladium-Catalyzed N-Arylation of Iminodibenzyls and Iminostilbenes with Aryl- and Heteroaryl Halides

Compounds containing the iminodibenzyl and iminostilbene ring systems are prevalent in medicinal targets and functional materials. Herein, we report palladium-catalyzed conditions for the N-arylation of these ring systems. This protocol could be applied to a variety of (hetero)aryl chloride and bromide substrates, including ones, which are sterically hindered or those containing a variety of functional groups. Use of the fourth-generation palladacycle precatalyst gave good to excellent yields by using low palladium-catalyst loadings (0.1 to 1 mol %).

Rigid triarylamine donor-π-acceptor porphyrin dyes and their application in dye-sensitized solar cells

Three donor-π-acceptor porphyrin dyes bearing a variety of rigid triarylamine donor groups were synthesized for application as photosensitizers in TiO2 based dye-sensitized solar cells (DSSCs). Compared with the "naked" porphyrin ZnP, i.e. havi

Performance improvement of dye-sensitizing solar cell by semi-rigid triarylamine-based donors

Novel organic dyes (IDB and ISB dyes), which contain 5-phenyl-iminodibenzyl (IDB) and 5-phenyl-iminostilbene (ISB) as electron donors and a cyanoacrylic acid moiety as an electron acceptor and an anchoring group, connected with a thiophene as a π-conjugated system, have been synthesized and used as the sensitizers for dye-sensitized solar cells (DSSCs). The photophysical and electrochemical properties of the dyes were investigated by absorption spectrometry, cyclic voltammetry and density functional theory calculations. As demonstrated, the IDB and ISB unit exhibited stronger electron-donating ability and broader absorption spectra when coated onto TiO2. The DSSC based on ISB-2 consisting of ISB unit produced 5.83% of η (Jsc = 13.14 mA cm-2, Voc = 0.64 V, and ff = 0.68) under 100 mW cm -2 simulated AM 1.5 G solar irradiation.
