Three new metal-free organic dyes FD1-3 with a planar dithieno[3,2-b: 2?,3?-d]pyrrole unit as linker were synthesized and used for dye-sensitized solar cells with high molar extinction coefficients. In this work, dithieno[3,2-b:2?,3?-d]pyrrole was employed as pi-conjugated bridge to construct A-pi-d-pi-A organic dyes, where 9,9-dihexyl-9H-fluorene was used as a donor, and cyanoacrylic acid as an electron acceptor. For a typical device, a solar energy conversion efficiency (eta) of 6.36% based on FD2 was achieved under simulated AM 1.5 solar irradiation (100 mW cm -2) with a short-circuit photocurrent density (Jsc) of 13.76 mA cm-2, an open-circuit voltage (Voc) of 669 mV, a fill factor (ff) of 0.691. The results suggest that the organic dye with a functionalized dithienopyrrole unit is a promising candidate for DSSCs due to its high molar extinction coefficients.

Palladium-catalyzed regio-, diastereo-, and enantioselective allylic alkylation of beta-ketocarbonyls with Morita?Baylis?Hillman adducts has been developed using a spiroketal-based diphosphine (SKP) as the ligand, thus affording a range of densely functionalized products bearing vicinal tertiary and all-carbon quaternary stereodyad in high selectivities. The utility of the protocol was demonstrated by the facile synthesis of some complex molecules by simple product transformations.

We report here a new strategy to produce 2,3,3-triarylacrylic acid esters, a class of 1,2,2-triarylethene compounds with an alpha,beta-unsaturated ester functionality. Our approach requires the preparation of a gem-dibromoalkene precursor from an alpha-keto ester, followed by the installation of two aryl groups by Suzuki-Miyaura coupling reactions on the two C-Br bonds. Many 2,3,3-triarylacrylic acid esters with one, two, or three different aryl groups were obtained with complete regio- and stereocontrol in most cases.

Polymeric acceptor based all-polymer solar cells have attracted wide interest due to their excellent mechanical properties. In order to combine the advantages of both the polymer and perylenediimide-based small-molecular acceptors, we designed and prepared a series of random copolymers via linking perylenediimide to the polymeric backbone of (naphthalenediimide/quinoxaline)-thieno[3,2-b]thiophene, which were successfully applied as polymer acceptors in solar cells. The effects of the pendant perylenediimide on the optical, electrochemical and photovoltaic performance were tuned via varying ratios of (quinoxaline-perylenediimide2) and naphthalenediimide. Atomic-force microscopic images showed that all random copolymers exhibited significantly improved miscibility with donor compared with an alternating copolymer reference, which coincided with the higher electron mobility measured by the space charge limited current method. The all-polymer solar cell based on the polymeric acceptor with high perylenediimide content achieved a power conversion efficiency of 4.81%. Although there is minimal conjugation between the perylenediimides and main chains, perylenediimides can also contribute to photocurrent generation.

An unprecedented palladium-catalyzed novel carbene/alkyne metathesis cascade reaction of alkyne-tethered enynones is described. This reaction affords fused polyheterocycles in moderate to good yields. The transformation begins with Pd-catalyzed 5-exo-dig cyclization of the enynone to form the donor/donor metal carbene, which then undergoes metathesis with the alkyne followed by electrophilic aromatic substitution.

By means of Sonogashira reaction, a series of 2-alkynyl- and 2,7-dialkynyl derivatives of 1,8-bis(dimethylamino)naphthalene (“proton sponge”) have been obtained from the corresponding iodides. It was disclosed that changing the reaction conditions and isolation protocol or conducting the model experiments with the authentic acetylenes results in several types of palladium- and copper-assisted heterocyclizations with the participation of the C?C bond and 1-NMe2 group. These include: (i) a cyclization into isomeric 1H-benzo[g]indoles with [1,3] migration of the N-methyl group into the newly formed pyrrole ring; (ii) a similar cyclization with a loss of the methyl group; (iii) a tandem process of cyclization into benzo[g]indoles and their subsequent 3,3?-dimerization; and (iv) a copper-catalyzed oxidative transformation into 3-aroylbenzo[g]indoles. In most cases, the reactions occur in parallel, but under certain conditions, one of the above products becomes predominant or even the only one. Remarkably, in Pd-catalyzed cyclizations i-iii, the acetylenic bond behaves as an electrophile being attacked at the beta-position by the amine nitrogen atom. In contrast, in transformation iv, the C?C bond attacks by its Calpha atom on the aminomethyl radical functionality N(Me)-CH2· presumably arising at copper oxidation/deprotonation of the 1-NMe2 group. Studying rearrangement i, some evidence for the porcelain catalysis was obtained.
