Department of Chemistry: Seminar 14 March 2014

Posted on March 11, 2014



The ineluctable and continuing depletion of fossil fuels poses one of the greatest challenges to mankind. Sunlight with its interminable radiation has been the source for all of the photosynthetic organisms, where energy storage is realized via chemical bond formation. Thus, photosynthesis, which has emerged as a blue print for solar energy storage, has motivated the application of “photosynthesis” fundamentals in the design of artificial reaction centers.

The advent of molecular conductors began in 1973 with the demonstration of charge transfer/charge transport in an organic metal, tetrathiafulvalene (TTF). In the following years, breakthroughs such as the introduction of interfacing two organic semiconductors, that is, an electron donor and an electron acceptor, paved the road to organic solar cells. The latter created a boom in the field of electron donor-acceptor systems as a means to generate spatially and electronically well isolated radical ion pairs.

In the present seminar, such wide variety of donor acceptor ensembles in terms of covalent and non-covalent systems with fullerenes as acceptor moieties shall be presented.
