Sentences with phrase «acceptor molecules»

Not exact matches

Oligothiophene (4T) and polythiophene (P3HT), two typical organic semiconductors, can be doped with a second type of molecule such as a strong electron acceptor (F4TCNQ) for example to control the electrical conductivity.

By manipulating the molecular distance between the electron - donating molecule (donor) and the electron - accepting molecule (acceptor) that carry the exciplex's hole and electron, respectively, the researchers could modify the properties of these weakly bound excitons.

«By increasing the thickness of an extremely thin layer of organic molecules inserted as a spacer between the donor and acceptor, we could reduce the attraction between the hole and electron in the exciplex and thereby greatly influence the exciplex's energy, lifetime, and emission color and efficiency.»

Abstract: Although it is known that molecular interactions govern morphology formation and purity of mixed domains of conjugated polymer donors and small - molecule acceptors, and thus largely control the achievable performance of organic solar cells, quantifying interaction - function relations has remained elusive.
