Spin Dynamics of Polaron Pairs in Organic Devices
关键字:Polaron Pairs
We characterize spin dependent kinetics ofpolaron pairs (PP) reactions in polymer organicdiodes based on a derivative ofpoly(phenylene-vinylene) [PPV], namely MEH-PPV as the active layer, using the dynamic response of the magnetic resonance ...

[ACS Macro Lett.] Lewis Pair-Mediated Surface-Initiated Polymerization
关键字:Lewis Pairs, Surface-Initiated Polymerization, Polymer Brushes
We present the first example of surface-initiated polymerization mediated by Lewis pairs for the synthesis of polymer brushes on planar substrates. The method enables the rapid grafting polymerization from the self-assembled monolayer or surface-attached macroinitiators, furnishing linear polymer brushes and bottle-brush brushes. Both homopolyester and block copolyester brushes can be synthesize...

Extensive development of precursory helical pairs prior to formation of trigonal stereocomplex crystals in racemic polylactide melt mixture
Melt crystallization of racemic polylactide (equimolar PLLA/PDLA) blend upon slow cooling (1 °C/min from 270 °C) was studied via a combination of wide-angle X-ray scattering (WAXS), differential scanning calorimetry (DSC), and Fourier-transfor...

Sharp Rise of Charge Mobility at High Density of Electron-Hole Pairs
关键字:electron-hole pairs
Sharp rise of conductivity by several orders of magnitude, which is caused by relatively small variations of electric field, pressure etc., was reported last 40 years, and its physical nature remains unclear1-4. High concentration ...

Highly Active Organic Lewis Pairs for the Copolymerization of Epoxides with Cyclic Anhydrides: Metal-Free Access to Well-Defined Aliphatic Polyesters
Polyester synthesis from the alternating copolymerization of epoxides with cyclic anhydrides via a metal-free route remains a key challenge. This work reports the development of a highly active organocatalytic route for the copolymerization of a spectrum of epoxides and cyclic anhydrides. Fully alternating polyesters were synthesized by a variety of organic Lewis acid?base pairs including organo...

Highly Efficient One-Pot Synthesis of COS-Based Block Copolymers by Using Organic Lewis Pairs
A one-pot synthesis of block copolymer with regioregular poly(monothiocarbonate) block is described via metal-free catalysis. Lewis bases such as guanidine, quaternary onium salts, and Lewis acid triethyl borane (TEB) were equivalently combined and used as the catalysts. By using polyethylene glycol (PEG) as the macromolecular chain transfer agent (CTA), narrow polydispersity block copolym...
