Perfectly Alternating and Regioselective Copolymerization of Carbonyl Sulfide and Epoxides by Metal-Free Lewis Pairs
The preparation of perfectly alternating and regioslective copolymers derived from the copolymerization of carbonyl sulfide (COS) and epoxides by metal-free Lewis pair catalysts composed of a Lewis base (amidine, guanidine, or quaternary onium salts) and a Lewis acid (triethyl borane) is described. Colorless and highly transparent copolymers of poly(monothiocarbonat...

102. Post-Functionalization of an Anderson-Type Polyoxomolybdate Using a Metal-Free Diels–Alder Click Reaction
Functionalization and post-functionalization of polyoxometalates (POMs) by organic groups or biological moieties can provide versatile platforms for creating novel functional hybrids with synergetic properties. Such materials can easily be envisioned as having many advanced applications in biology and materials science. Nowadays, the organic groups or biological moieties used for conjugation with ...

Metal-Free Route to Precise Synthesis of Poly(propylene oxide) and Its Blocks with High Activity
关键字:Metal-Free,propylene oxide,High Activity
The fast and living ring-opening polymerization (ROP) of propylene oxide (PO) by metal-free catalysis is reported. By using triethyl borane (TEB) and organic Lewis bases (LBs, e.g.: phosphazene base, amidine and guanidine) as the catalysts, various alkyl alcohols can effectively initiate the ROP of PO, yielding tailor-made poly(propylene oxide)s (PPOs) with high regioregularity, predictable mole...

Dithiafulvenyl unit as a new donor for high-efficiency dye-sensitized solar cells: Synthesis and demonstration of a family of metal-free organic sensitizers.
This work identifies the dithiafulvenyl unit as an excellent electron donor for constructing D?π–A-type metal-free organic sensitizers of dye-sensitized solar cells (DSCs). Synthesized and tested are three sensitizers all with this donor and a cyanoacrylic acid acceptor but differing in the phenyl (DTF-C1), biphenyl (DTF-C2), and phenyl–thiopheneyl–phenyl π-bridges (DTF-C3). Devices based o...

Efficient Metal-Free Organic Sensitizers Containing TetraphenylethyleneMoieties in the Donor Part for Dye-Sensitized Solar Cells
关键字:Donor–acceptor systems, Dyes/pigments, Sensitizers, Solar cells, Energy conversion
Two new propeller-shaped D-π-A organic sensitizers that contain two tetraphenylethylene (TPE) moieties in the donor part of the triphenylamine group have been designed and characterized. These dyes are composed of the same donor and acceptor units with different aromatic units introduced through linkers between the donor and acceptor units. The dye-sensitized solar cells (DSCs) based on LI-31 wit...
