Stimuli-responsive supramolecular assembly has been studied extensively as a forward-looking technology for the precise control of the physical properties and functions of aggregates. Our group developed a new methodology for the instant gelation of stable organic fluids including dinuclear Pd complex, anti-1, by brief irradiation with ultrasound. This phenomenon is the first example of the instant and remote control of sol-gel transition, and attracts our interest in the development of functional complexes based on gelation phenomena. New metal complexes, that have various kind of substituents, metals, spacers, have been synthesized, and the properties of these complexes were examined. A basic knowledge on the mechanism of the new-fashioned gelation was obtained by carrying out spectroscopic methods such as NMR, UV-vis spectra, and direct observation of morphology by scanning electron microscope and atomic force microscopy. In addition, we established a new concept of "aggregation polymerization." Based on this concept we succeeded to demonstrate a new type of aggregation mode, living aggregation.

刺激响应型超分子组装技术作为一种具有前瞻性的技术，在精确控制聚集体的物理性质和功能方面得到了广泛的研究。我们的小组开发了一种新的方法，通过短暂的超声波照射，包括双核钯配合物，反-1的稳定的有机流体的即时凝胶化。这一现象是溶胶-凝胶转变的即时和远程控制的第一个例子，并吸引了我们在基于凝胶化现象的功能复合物的发展的兴趣。合成了具有各种取代基、金属、间隔基的新型金属配合物，并对这些配合物的性质进行了研究。通过NMR、UV-vis等光谱分析方法，以及扫描电镜和原子力显微镜对凝胶形态的直接观察，对新型凝胶化的机理有了初步的认识。此外，我们还建立了“聚集聚合”的新概念。“基于这一概念，我们成功地展示了一种新型的聚合模式，即生活聚合。
