Charge-Transfer Interactions in Organic Functional Materials

Our goal in this review is three-fold. First, we provide an overview of a number of quantum-chemical methods that can abstract charge-transfer (CT) information on the excited-state species of organic conjugated materials, which can then be exploited for the understanding and design of organic photodiodes and solar cells at the molecular level. We stress that the Composite-Molecule (CM) model is...

The synthesis and purification of amphiphilic conjugated donoracceptor block copolymers

Nanoscale domains of donor and acceptor materials are crucial for charge generation in organic photovoltaic devices. These domains are difficult to achieve reproducibly in blended materials, but could be engineered into single-material active layers composed of donor–acceptor block copolymers (BCPs). In this work, we report the synthesis and purification of two novel fully conjugated BCPs, P3HT...

Ion-induced formation of charge-transfer states in conjugated polyelectrolytes.

We use time-resolved optical spectroscopy to demonstrate that the luminescence quenching observed when ions are incorporated in films of conjugated polymers can be explained by the formation of charge-transfer (CT) states that are stabilized by the Coulomb field of ions. Our investigation is focused on a conjugated polyelectrolyte (CPE) derived from F8BT (poly(9,9'-dioctylfluorene-alt-benzothia...

Charge-transfer complexes of some linear conjugated polyenes.

On adsorption of some electron-acceptor molecules on the solid films of all-trans-beta-carotene, beta-apo-8'-carotenal, astacene and methylbixin a new absorption band appears on the longer-wavelength side of the spectrum in addition to the original bands. The position of this new band is dependent on the electron affinity (EA) of the acceptor molecules, and the intensity of this band increases ...

Donor-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...
