详细
The dimensional effect previously observed in various matrices for 2,6-polyphenylquinoline containing oxygen bridge and carbazolediyl groups is confirmed for phenylamine-containing 2,6-polyphenylquinolines with carbazole- and indolocarbazolediyl moieties in a polymethyl methacrylate matrix. The effect is observed from the dependence of the luminescence parameters (intensity and peak position) on the film thickness and poly-4-phenylquinoline concentration in the matrix. It is shown that the luminescence intensity decreases as the film thickness decreases to less than 50 micrometers and at distances 〈D〉 between molecules in the composite of less than 9 nm, with the peak position shifted to shorter wavelengths. The dependence of the luminescence intensity on 〈D〉 has a clearly pronounced maximum at 6–9 nm.
