报道了一种双通道可切换的纳米级混合系统，该系统能够通过光响应附加的有机基团和作为分子帽的G1.5 PAMAM树枝状聚合物的存在来调节质量传递。这种新的功能性门状系综在纯水溶液中受到化学（通过pH变化）和光化学（使用可见光）控制，如涉及染料控释的实验所示（见图）。
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).
