Nanocomposite layers 250 nm copper phthalocyanine/polyimide prepared by simultaneous vapour deposition of three different sources were studied. Different concentrations of copper phthalocyanine as a "guest" in polyimide matrix as a function of conditions of the preparation have been determined by FTIR (Fourier Transform Infrared) and UV-VIS (Ultraviolet-Visible) spectroscopies. The aim was to estimate the possibility of the spectroscopic methods for quantitative determination of the "guest" and compare with the quality of the polyimide thin films in relation to the "guest" concentration. The band at 1334 cm(-1) has been used for quantitative estimation of "guest" in polyimide matrix. The concentrations of the copper phthalocyanine less than 20% require curve fitting techniques with Fourier self deconvolution. The relationship between "guest" concentrations and degree of imidization, as well as the electronic UV-VIS spectra are discussed in relation to the composition, imidization degree and the two crystallographic modification of the embedded chromophore.
研究了通过同时蒸镀三种不同源制备的250纳米铜酞菁/聚酰亚胺纳米复合层。通过傅里叶变换红外光谱（FTIR）和紫外-可见光谱（UV-VIS）确定了作为聚酰亚胺基体中“客体”的不同浓度铜酞菁随制备条件的变化情况。目的是评估光谱方法定量测定“客体”的可能性，并与聚酰亚胺薄膜质量与“客体”浓度的关系进行比较。1334厘米-1处的谱带已用于定量估计聚酰亚胺基体中的“客体”。铜酞菁浓度低于20%时需要采用傅里叶自去卷积的曲线拟合技术。讨论了“客体”浓度与亚胺化程度之间的关系，以及与嵌入发色团的组成、亚胺化程度和两种晶体学改性相关的电子紫外-可见光谱。
