In this communication we investigate two dyes N,N'-dioctadecyl thiacyanine perchlorate (NK) and octadecyl rhodamine B chloride (RhB) in Langmuir and Langmuir-Blodgett (LB) films with or with out a synthetic clay laponite. Observed changes in isotherms of RhB in absence and presence of nano-clay platelets indicate the incorporation of clay platelets onto RhB-clay hybrid films. AFM images confirm the incorporation of clay into hybrid films. FRET is observed in clay dispersion and LB films with and without clay. Efficiency of energy transfer is maximum in LB films with clay.
在本通讯中，我们研究了两种染料 N,N'-十八烷基硫氰酸高氯酸盐（NK）和十八烷基罗丹明 B 氯化物（RhB）在 Langmuir 和 Langmuir-Blodgett（LB）膜中的情况，有无合成粘土锂蒙脱石。在不存在和存在纳米粘土薄片的情况下，观察到 RhB 等温线的变化表明粘土薄片掺入到 RhB-粘土杂化膜中。原子力显微镜图像证实了粘土的掺入到杂化膜中。在有和没有粘土的粘土分散体和 LB 膜中观察到 FRET。在含有粘土的 LB 膜中能量转移效率最大。
