| Challenge:
Understand the molecular scale organization of chromophores and how macroscopic order can be improved by addition of dendrimers.
|
Approach:
We are modeling various dendrimer structures to determine optimal geometries with and with out external poling fields. We are optimizing chromophore connectivities within the dendrimer framework to produce larger EO responses. |
Impact:
Shown below are six prolate chromophores linked by deformable connectors. Under the influence of a poling field they spontaneously align. Interlacing of the two arms reinforces the dipolar interactions. Construction of such chromophores is underway. |
