以三（邻苯二氧基）环三磷腈（TPP）为模板化合物，采用真空吸附和缓慢重结晶两种方法，合成了一种新的一维有机自由基包合物（2，2，6，6-四甲基-1-哌啶氧基（克里思））。通过热重分析（TG），粉末XRD和ESR测量，克里思分子在TPP 1D纳米通道中的排列得到证实。克里思分子被容纳在TPP纳米通道中而没有分解，并且以克里思分子中的氮氧基团的取向垂直于纳米通道的轴排列。TPP/克里思包合化合物可包括克里思分子，在TPP晶格中每个晶胞至多一个分子。
A new inclusion compound with a one-dimensional molecular arrangement of organic radicals (2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)) was prepared using the template compound of tris(o-phenylenedioxy)cyclotriphosphazene (TPP) by the following two methods: i) adsorption of TEMPO vapor under vacuum at 313 K and ii) slow recrystallization in mesitylene. The arrangement of TEMPO molecules in the TPP 1D nanochannel was confirmed by thermogravimetric analysis (TG), powder XRD and ESR measurements. TEMPO molecules were accommodated in the TPP nanochannel with no decomposition, and were arranged with the orientation of the nitroxide group in the TEMPO molecule perpendicular to the axis of the nanochannel. The TPP/TEMPO inclusion compound can include TEMPO molecules up to one molecule per unit cell in the TPP crystal lattice.
