Proton/Electron-Donors Enhancing Electrocatalytic Activity of Supported Conjugated Microporous Polymers for CO2 Reduction.

Angewandte Chemie, 2021
Metal phthalocyanines (MePc) hold great promises in electrochemical reduction of CO2 to value-added chemicals, whereas the catalytic activity of MePc-containing polymers often suffers from the limited molecular modulation strategy.

Rational Design of MOF/COF Hybrid Materials for Photocatalytic H2 Evolution in the Presence of Sacrificial Electron Donors.

Angewandte Chemie, 2018
Crystalline and porous covalent organic frameworks (COFs) and metal-organic frameworks (MOFs) materials have attracted enormous attention in the field of photocatalytic H2 evolution due to their long-range order structures, large surface areas ...

Atom‐Economic Electron Donors for Photobiocatalytic Halogenations

ChemCatChem, 2018
In vitro cofactor supply and regeneration have been a major obstacle for biocatalytic processes, in particular on a large scale. Peroxidases often suffer from inactivation by their oxidative co‐factor.

New π-Electron Donors

Molecular Crystals and Liquid Crystals Incorporating Nonlinear Optics, 1990
Abstract The synthesis of a series of new donor molecules, 1,6-dioxa-pyrenes, is reported. Also reported is a series of dimeric TTF systems. For the dimeric TTF structures the implications for the Fermi surface in 1:1 donor-acceptor salts are discussed. Preliminary results for a few new conducting salts derived from the dimeric TTFs are given.

Photoinduced Electron Transfer in a Mesogenic Donor–Acceptor–Donor System

Chemistry - A European Journal, 2002
A novel donor-acceptor-donor molecule consisting of two oligo(p-phenylene vinylene) (OPV4) units attached to a central perylene bisimide (PERY) core is described. This OPV4-PERY-OPV4 is the first mesogenic molecule that incorporates both p- and n-type semiconducting properties and possesses a liquid-crystalline mesophase, in which donor and acceptor ...

Electron tunneling from donors and excitons

Solid-State Electronics, 1988
Abstract Experimental results on elastic tunneling of electrons from shallow levels in uniformly doped bulk semiconductors are reviewed. Recent observation of the tunneling in nanosecond time range has stimulated development of transient tunneling spectroscopy, which can yield information on the tunneling parameters, level spectrum and non-steady ...

Electron donor-acceptor properties of haematoporphyrin

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1968
Abstract 1. The interaction of haematoporphyrin with a wide range of electron donors has been studied spectrophotometrically in phosphate buffer solution at pH 9 where the spectrum is insensitive to small changes of pH. 2. It has been shown that haematoporphyrin forms 1:1 complexes, the difference spectra being temperature reversible and containing ...

Making Benzotrithiophene a Stronger Electron Donor

Organic Letters, 2011
A new member of the benzotrithiophene family, benzo[2,1-b:-3,4-b':5,6-c″]trithiophene (3a), and its alkyl substituted derivatives (3b-e) were synthesized and characterized. Their photophyscial, electrochemical, crystallographic, and self-assembly properties were described.
