Evanescent Waveguide Characterization and Photoisomerization of ALL-Azobenzene Functionalized Dendrimers on Ultrathin Films:Aggregation Behavior and Matrix Effects

摘要

Dendrimers are a new class of macromolecular characterized by their three-like generational structure.Recenlty,the design,synthesis,and functional chemistry of these dendrimers have attracted increased attention.One of the interesting features of dendrimers is that their shape can be modeled and controlled by parameters related to their non-covalent interactions with their surrounding environment,e.g.steric and dipole factors.
