Intramolecular electronic energy transfer in rhodamine–azulene bichromophoric molecule
2007
Abstract Electron transfer and electronic energy transfer (EET) processes are ways by which different molecules can interact, signalling their state, by EET from a donor (D) to an acceptor (A). This D–A transfer is often observed in an intermolecular process but it can also occur intramolecularly, that is between two bridged parts of a bichromophoric molecule. In this paper we present results pertaining to electronic energy transfer in a newly synthesized rhodamine–azulene (Rh–Az) a bichromophoric molecule, in which a full adder can be implemented. The intramolecular EET rate constant in the Rh–Az molecule was found to be 7.81 × 10 9 s −1 .
