描述了第一个通过超声波组装的分子。缔合惰性双核 Pd 络合物 anti-1a 通过分子内 π 堆积相互作用稳定，在短暂的预超声处理几秒钟后立即胶凝各种有机溶剂。这是第一种用于远程切换稳定溶胶-凝胶相的快速、积极且可逆的方法。独特的是，只需调整超声处理时间，即可在“无凝胶化”和“即时凝胶化”之间的范围内精确控制速率。
The first molecule that assembles by ultrasound is described. An association-inert dinuclear Pd complex,anti-1a, which is stabilized by intramolecular π-stacking interactions, gelatinizes a variety of organic solvents instantly upon brief presonication for a few seconds. This is the first quick, positive, and reversible method for the remote switching of stable sol-gel phases. Uniquely, the rate can be precisely controlled over the range between “no gelation” and “instant gelation” simply by tuning the sonication time.
