Design & Synthesis of Branched Self-Assembling Chromophore

Design & synthesis of branched (“dendritic”) chromophore-- Self-assembles to provide a material with high performance for information technology applications.

Impact:
Ultrahigh E-O activity of these materials will enable the design and fabrication of innovative devices with very low drive voltage and compact size. It will also offer the possibility to realize direct integration on Si chips. This development provides a new paradigm for information technology with ultrahigh speed and very large bandwidth.

Major companies including Boeing, Lockheed-Martin, and Battelle are working with CMDITR researchers to explore the potential of these materials.
Dendritic Chromophore has an electric dipole from donor/acceptor region (red). H- and F-dendrons (purple & black) help self-assembly. Self-assembly of H- and F-dendrons facilitates excellent alignment of dipoles & stability needed for high E-O activity.
