Photonic applications of the supermolecular nanostructures with photophysical processes controlled

A hyper-branched molecule, such as a dendrimer, has a repeated structure consisting of molecules with low molecular weights. As it is possible to produce relatively large and well-defined macromolecular structures, these structures are suitable for use as frameworks for controlling nanoscale intermolecular interactions. We discuss about managing intermolecular interactions among optical responsive molecules using the framework of super molecular structures, such as dendrons and dendrimers. The dendrimer works as a nano-sized cage, which is effectively protect photoactive choromophores from photobleaching and quenching. The dendron works as a cone-shaped anchor, which leads effective surface modification with photoactive molecules on gold.
