4-substituted-2,2,6,6-tetramethyl-1-piperidinyloxyl radical) with 1D organic-radical molecular chains constructed in organic 1D nanochannels used as templates were conducted in the range of temperatures from 4.2 to 300 K. The peak-to-peak line width (ΔBpp) of all isotropic ESR spectra of the [CLPOT-(4-X-TEMPO)] was much narrower in the whole temperature range than the estimation based on the Van Vleck’s formula
[CLPOT-(4-X-TEMPO)] 包合物的 ESR 测量值 (CLPOT = 2,4,6-tris(4-chlorophenoxy)-1,3,5-triazine, 和 4-X-TEMPO = 4-取代-2,2,6,6-四甲基-1-哌啶氧基自由基)在用作模板的有机一维纳米通道中构建的一维有机自由基分子链在4.2至300 K的温度范围内进行。峰到峰[CLPOT-(4-X-TEMPO)] 的所有各向同性 ESR 光谱的线宽 (ΔBpp) 在整个温度范围内比基于刚性晶格模型二阶矩的 Van Vleck 公式的估计要窄得多。此外,[CLPOT-(4-X-TEMPO)] 的所有 ESR 谱的谱线在整个温度范围内都变成了洛伦兹,与我们之前使用三(邻苯二氧基)环三磷腈(TPP)作为模板的结果相比,ESR 曲线与温度有关。这些结果表明 [CLPOT-(4-X-TEMPO)] 较窄的 ESR 线宽可能不是由运动变窄引起的,而是由
