All Optical Full Adder Based on Intramolecular Electronic Energy Transfer in the Rhodamine-Azulene Bichromophoric System

摘要

Charge and electronic energy transfer(ET and EET)are well-studied examples whereby different molecules can signal their state from one(the donor,D)to the other(the acceptor,A).The electronic energy transfer from the donor(Rh)to the acceptor(Az)is used to build an all-optical full adder on a newly synthesized bichromophoric molecule Rh-Az.The results are supported and interpreted by a full kinetic simulation.It is found that the optimal design for the implementation of the full adder relies in an essential way on the intramolecular transfer of information from the donor to the acceptor moiety.However,it is not the case that the donor and the acceptor each act as a half adder.
