Benzimidazole derivative and 8-hydroxyquinoline derivative cadmium complex dye sensitizer as well as preparation method and application thereof

The invention relates to a D (-A-pi-A) 2 type benzimidazole derivative and 8-hydroxyquinoline derivative cadmium complex dye sensitizer (BDTT-bi-Cd) as shown in a formula 1 as well as a preparation method and application of the BDTT-bi-Cd. The dye sensitizer is a D (-A-pi-A) 2 type complex synthesized by reacting benzimidazole containing functional groups such as an auxiliary electron acceptor (A), a pi bridge, a main electron acceptor (A) and an anchoring group with a 8-hydroxyquinoline derivative cadmium complex and an electron donor (D) benzodithiophene bithiophene (BDTT) through a Heck coupling reaction. Experiments show that the photovoltaic performance test of a dye-sensitized solar cell with the BDTT-bi-Cd as the dye sensitizer shows good effects that the photoelectric conversion efficiency (PCE) reaches 8.40%, the dye thermal decomposition temperature reaches 320 DEG C or above, the thermal stability is high, the requirements of photovoltaic materials can be met, and the complex dye sensitizer has a certain prospect in the aspect of development and application of the dye-sensitized solar cell. The structure of the complex BDTT-bi-Cd shown in the formula 1 is shown in the specification.

Novel metal complexes for D-(A-π-A)2 motif dye sensitizer: Synthesis and photovoltaic application

Four metal complexes BDTT-PCd, BDTT-PZn, BDTT-PCu, and BDTT-PCo with the symmetrical structure were designed, synthesized, and characterized, which would be used as D-(A-π-A)2 motif dye sensitizers. These complexes adopt Cd(II), Zn(II), Cu(II), and Co(II) complexes as auxiliary electron acceptors (A), thienylbenzo[1,2-b:4,5-b′]dithiophene (BDTT) as electron donor (D), and the 8-quinolinol derivative as the π bridge and the acceptor (A) of D-(A-π-A)2 motif dye sensitizers. The photophysical, electrochemical, and photovoltaic properties of these complexes have been investigated. The four complexes-based dye-sensitized solar cells (DSSCs) device exhibited a short-circuit photocurrent density (Jsc) of 17.51, 17.02, 15.07, and 14.38 mA cm?2 and an attractive power conversion efficiency (η) of 8.82%, 8.32%, 8.03%, and 7.55%, respectively, under the AM 1.5 irradiation (100 mW cm?2). The photovoltaic conversion efficiency (PCE) and the short-circuit photocurrent density (Jsc) of BDTT-PCd, BDTT-PZn, BDTT-PCu, and BDTT-PCo are sequentially reduced; it attributed to the difference of the electron-withdrawing ability of the auxiliary acceptor resulted by the difference of coordination abilities of metal ions Cd(II), Zn(II), Cu(II), and Co(II) with ligand. These results provide strong evidence that D-(A-π-A)2 motif complexes has great potential as promising photosensitizers in the applications of DSSCs.

Heck cross-coupling for synthesizing metal-complexing monomers

New polymerizable ligands for complexing metal ions have been synthesized. The polymerizable ligands were made by Heck cross-coupling of aromatic bromides with high pressure ethylene gas under mild conditions at room temperature. The vinyl substituted ligands were prepared in good yields and characterized by GC-MS, FT-NMR, FT-IR and microanalysis. Georg Thieme Verlag Stuttgart.

Polymer complexes XXXVII novel models and structural of symmetrical poly-Schiff base on heterobinuclear complexes of dioxouranium(VI)

Some binary and ternary novel complexes of dioxouranium(VI) with 5-vinylsalicylaldehyde (VSH) have been prepared and characterized by various physico-chemical techniques. The amine exchange reactions of coordinated poly-Schiff bases in these complexes have been also carried out which give symmetrical tetradentate poly-Schiff base complexes. Metal exchange reaction of these dioxouranium(VI) complexes with copper(II) gives the corresponding Cu(II) complexes. Reaction of tetradentate poly-Schiff base complexes of Cu(II) so obtained with ZrCl4 gives heterobinuclear polymer complexes. Magnetic, electronic and IR spectral information commensurate that configurations of square planar copper(II) polymer complexes. All the polymer complexes are coloured and appear to be nonelectrolytes in DMF. The ligands behave as bi-(O, O) and tetradentate (N2, O2) donors. El-Sonbati equation was used to evaluate the symmetric stretching frequency from which the fU-O and fUO, UO- were calculated.
