Donor-pi-acceptor conjugated copolymers for photovoltaic applications: tuning the open-circuit voltage by adjusting the donor/acceptor ratio.
A class of new conjugated copolymers containing a donor (thiophene)-acceptor (2-pyran-4-ylidene-malononitrile) was synthesized via Stille coupling polymerization. The resulting copolymers were characterized by 1H NMR, elemental analysis, GPC, TGA, and DSC. UV-vis spectra indicated that the increase in the content of the thiophene units increased the interaction between the polymer main chains t...
متن کاملDonor-Acceptor Conjugated Molecules: Charge Transfer, Mechanism and Significance
Donor-acceptor molecules with charge transfer behavior have received a great deal of attention because of their critical role in industrial and biological applications. In this context, numerous studies on the donoracceptor molecules were carried out in recent years. In this article, some of the mentioned aspects have been discussed in detail. Received date: 03/09/2015 Accepted date: 23/12/2015...
متن کاملDonor-acceptor-acceptor (D-A-A) type 1,8-naphthalimides as non-fullerene small molecule acceptors for bulk heterojunction solar cells.
Donor-acceptor-acceptor (D-A-A) type 1,8-naphthalimide based small molecules SM1 and SM2 functionalized with tetracyanobutadiene (TCBD) and dicyanoquino-dimethane (DCNQ) modules, showing strong absorption in the visible and near-infrared (NIR) region are reported. TCBD and DCNQ linked SM1 and SM2 exhibit multi-redox waves. The electrochemical and optical HOMO-LUMO gaps show similar trends. Thes...
متن کاملUltrafast Photoinduced Electron Transfer in Spiro-type Donor- Acceptor Systems
Perpendicular orientation of the electron donor in relation to the acceptor in the ground state seems to contribute significantly to high rate constants of the photoinduced intramolecular electron transfer (PET) in electron donor-acceptor (DA) type molecules [1]. A very interesting class of molecules in this respect are systems build around a spiro-type carbon atom, separating mutually orthogon...
متن کاملRapid bulk replacement of acceptor membrane by donor membrane during phagosome to phagoacidosome transformation in Paramecium.
The extent to which a donor membrane will be retrieved, or if it is retrieved at all after it fuses with an acceptor membrane, is usually difficult to determine. We have studied the dynamics of membrane retrieval in the phagosome system of Paramecium multimicronucleatum using six monoclonal antibody markers. Our previous freeze-fracture and transmission electron microscopic studies have indicat...
