Pi-delocalizable dendrimers

Dendrimers are highly branched molecules that are of interest for applications in medical diagnostics, molecular recognition, catalysis, and photoactive device engineering. We have prepared unique π-delocalizable dendrimers and are examining their electrochemical, optical, and particularly nonlinear optical (NLO) properties. Materials with NLO properties can modify the propagation characteristics of light beams (frequency, phase, path, etc) and so are important for potential applications in optical communications, data storage, and a variety of other areas, all of which are undergoing explosive growth, and in all of which chemists can make crucial contributions.
