Two functional dyes were integrated by intercalating guest dyes into the solid-state two-dimensional nanospace of a coumarin/phyllosilicate hybrid, wherein the coumarin moiety was anchored covalently to the phyllosilicate moiety. Ultraviolet. visible spectroscopy and X-ray diffraction analysis showed that the mole ratios of the guest dye to the coumarin moiety([Guest]/[Coum]) ranged from 0.004to40mol/mol. Fluorescence spectroscopy revealed that both the coumarin moieties and gust dyes fluoresced. Furthermore, in the case of the integrated coumarin/3, 3'-diethyloxacarbocyanine(DOC) systems, the guest dye(DOC) even emited by excitation at320nm due to energy transfers within the integrated coumarin/DOC systems. The extent of the energy transfers and fluorescence intensities depended on[DOC]/[Coum]. The proposed models of the arrangements of the fluorophores for the integrated dyed systems consist of the coumarin moieties located on both close to and far from the guest dyes in the same two-dimensional nanospace with the guest dyes always in close proximity to a coumarin moiety. These unique arrangements of fluorophores allow two types of fluorescence behavior for the integrated coumarin/DOC systems :(1) fluorescence resonance energy transfer(FRET) from the excited coumarin moiety located close to DOC and(2) radiative energy transfer.

通过将客体染料嵌入香豆素/页硅酸盐杂化物的固态二维纳米空间中来整合两种功能染料，其中香豆素部分共价锚定到页硅酸盐部分。紫外线。可见光谱和X射线衍射分析表明，客体染料与香豆素的摩尔比（[客体]/[香豆素]）为0.004 ~ 40 mol/mol。荧光光谱显示，香豆素部分和阵风染料发荧光。此外，在香豆素/3，3 '-二乙基氧杂碳菁（DOC）的复合体系中，由于复合体系中的能量转移，客体染料（DOC）甚至可以在320 nm激发下发光。能量转移的程度和荧光强度取决于[DOC]/[Coum]。所提出的模型的安排的荧光团的综合染色系统的香豆素部分位于两个接近和远离客体染料在同一个二维纳米空间与客体染料总是在接近香豆素部分。这些独特的荧光团排列使得集成的香豆素/DOC系统具有两种类型的荧光行为：（1）来自靠近DOC的受激香豆素部分的荧光共振能量转移（FRET）和（2）辐射能量转移。
