Electronic Energy Transfer in a Supramoiecular Species Containing the [Ru(bpy)_3]~(2+), [Os(bpy)_3]~(2+) , and Anthracene Chromophoric Units

摘要

At the roots of suprumolecular chemistry is the concept that supramolecular systems have the potential to achieve much more elaborate tasks than simple molecules: while molecules can be involved in simple chemical acts, supramolecular systems can perform functions. In other words. suprurnoleculdr systems have the potential to behave as molecular duvices. A particularly interesting class of molecular devices is that capable of using photons as energy or information inputs (photochemical molecular devices). An essential function in many photochemical molecular devices is electronic energy transfer. The design of ordered supramoiecular systems in which the path of electronic energy transfer can be synthetically predetermined and then switched by an external input is an important goal of current chemical research.
