Development of new conjugated polymers with donor-π-bridge-acceptor side chains for high performance solar cells

(Graph Presented) Two new conjugated polymers have been designed and synthesized for polymer solar cells. Both of them exhibit excellent photovoltaic properties with a power conversion efficiency as high as 4.74%. Different from the traditional linear don

Suzuki polycondensation and post-polymerization modification toward electro-optic perfluorocyclobutyl (PFCB) aryl ether polymers: Synthesis and characterization

Suzuki polycondensation (SPC) as an alternative strategy has been utilized for the first time to readily yield functional perfluorocyclobutyl (PFCB) aryl ether polymers, which are difficult to obtain via the traditional [2+2] thermal cyclopolymerization s

Reaction-based probe for hydrogen sulfite: dual-channel and good ratiometric response

We designed and synthesized a new series of intramolecular charge transfer (ICT) molecules (compounds T1, T2 and T3) by attaching various electron-donating thiophene groups to the triphenylamine backbone with aldehyde group as the electron acceptor. Based on the nucleophilic addition reaction between hydrogen sulfite and aldehyde, all compounds could act as ratiometric optical probe for hydrogen sulfite and displayed efficient chromogenic and fluorogenic signaling. Upon the addition of hydrogen sulfite anions, probe T3 displayed apparent fluorescent color changes from yellowish-green to blue, with a large emission wavelength shift (Δλ = 120?nm). T3 responded to hydrogen sulfite with high sensitivity and the detection limit was determined to be as low as 0.9?μM. At the same time, apparent changes in UV–vis spectra could also be observed. By virtue of the special nucleophilic addition reaction with aldehyde, T3 displayed high selectivity over other anions. Copyright

Poly (triphenylamine-fluorenylmethylchloroformate) dye and its application

The invention discloses a poly(triphenylamine-fluorene) dye and its application. The poly(triphenylamine-fluorene) dye is prepared through a Stille coupling reaction of a monomer having a triphenylamine structure and a monomer having a fluorene structure. The prepared poly(triphenylamine-fluorene) dye has a triphenylamine and fluorene composite donor unit structure, and can be applied in the production of dye-sensitized solar cells in order to obtain dye-sensitized solar cells with high current density and high photoelectric conversion rate.

Fluorescent and colorimetric probes for mercury(II): Tunable structures of electron donor and π-conjugated bridge

A new series of intramolecular-charge-transfer (ICT) molecules (compounds 1, 2, and 3) were synthesized by attaching various electron-donating thiophenes groups to a triphenylamine backbone with an aldehyde group as the electron acceptor. Based on the protection reaction between ethanethiol and aldehyde, the corresponding dithioacetals (compounds S1, S2, and S3) were prepared to serve as novel colorimetric and fluorescent chemosensors for Hg2+ ions. Also, compound S1 was further utilized to construct the chemical-reaction-based conjugated polymer probe (PS1) towards Hg2+ ions. In the presence of as little as 10 nM Hg2+, compound PS1 displayed an apparent change in the fluorescent intensity. The sensing processes were revealed to be mediated by ICT, as confirmed by time-dependent DFT calculations. Furthermore, compound S1 was successfully applied to microscopic imaging for the detection of Hg 2+ in HeLa cells with ratiometric fluorescent methods. Copyright
