通过在含有二十烷酸镉的Langmuir-Blodgett （LB）膜中加入少量触发分子正六正康烷（ch3 (ch2) 34 ch3）来控制功能分子PM（3,5-二-丁基苯基）卟啉铜（II）的取向。采用电子自旋共振（ESR）和紫外/可见吸收光谱研究了PM/二十烷酸镉/正六正康烷摩尔混合比为1.5/10/x的混合LB膜在0≤x≤5范围内的取向。ESR谱分析表明，在LB膜中存在两种不同取向的PM组分
The orientation of the functional molecule PM, tetrakis(3,5-di-t-butylphenyl)porphinatocopper(II), was controlled by adding a small amount of the trigger molecule, n-hexatriacontane (CH 3 (CH 2 ) 34 CH 3 ) in the mixed Langmuir-Blodgett (LB) films with cadmium icosanoate. The orientation of PM was investigated by using the electron spin resonance (ESR) and UV/vis absorption spectroscopies for mixed LB films with the molar mixing ratio PM/cadmium icosanoate/n-hexatriacontane=1.5/10/x in the range 0≤x≤5. The ESR spectra showed that there were two PM components, having different orientation, in each of the LB films
