Dendrimers and Hyperbranched Polymers

A two-channel switchable nanoscopic hybrid system, able to modulate mass transport by photoresponsive appended organic groups and the presence of G1.5 PAMAM dendrimers as molecular caps, is reported. This new functional gatelike ensemble is chemically (by pH changes) and photochemically (using visible light) controlled in pure aqueous solution, as demonstrated by an experiment involving the controlled release of a dye (see figure).
