在本文中,我们报告了通过相应的三炔与钴催化剂的三聚反应合成了圆形排列的六节三烯齿轮分子六(10-十二烷氧基-9-三苯乙烯基)乙炔基苯。单晶 X 射线结构分析证实,六个三苯乙烯齿轮彼此紧密啮合,核磁共振光谱确定了它们在溶液中的运动。值得注意的是,当一个笨重的 RuCp* 复合物连接到一个三烯齿轮时,六个齿轮的整个运动通过它们的机械啮合受到高度限制。这种多齿轮分子的开发将为具有切换功能的分子运动传输系统提供结构基础。

A conventional polymerization inhibitor is for example an agent to scavenge radicals generated during storage of a radical polymerizable compound and used to stably handle the radical polymerizable compound, but is unnecessary when the radical polymerizable compound is to be subjected to radical polymerization reaction, and is preferably removed at the time of the radical polymerization reaction. The object of the present invention is to obviate inconvenience of removing the polymerization inhibitor at the time of radical polymerization.
The radical polymerization control agent contained in a radical polymerizable composition of the present invention functions as a radical polymerization inhibitor for example stored in a dark place, but loses its radical polymerization inhibiting effect when polymerization is initiated while being irradiated with light at a certain specific wavelength at the time of polymerization. Thus, radical polymerization of the radical polymerizable compound is easily initiated without increasing the amount of a radical polymerization initiator. That is, the radical polymerization control agent of the present invention is a radical polymerization control agent which is a corn pound having an effect to inhibit radical polymerization of a radical polymerizable compound and which loses the radical polymerization inhibiting effect under irradiation with light rays containing light within a wavelength range of from 300 nm to 500 nm.
