| 摘 要： | Two generations of earboxyl-terminated poly (aryl ether) dendrimers bearing 9,10-diphenylanthracene cores are designed and synthesized. Alternating deposition of two dendrimers and poly(4-vinylpyridine) is studied with UV-Vis spectroscopy, FT-IR spectroscopy and atomic force microscopy. Experimental results indicate that this method to introduce chromophore into multilayer film can effectively prevent desorption of dye molecule. Moreover, it is found that dendrimer can inhibit the aggregation of fluorophore in film using fluorescence spectroscopy. Increase of dendrimer‘s generation can enhance fluorescence intensity of each fluorophore. This provides a new approach to design luminescent thin film.

| Abstract: | Two generations of carboxyl-terminated poly (aryl ether) dendrimers bearing 9, 10-diphenylanthracene cores are designed and
synthesized. Alternating deposition of two dendrimers and poly(4-vinylpyridine) is studied with UV-Vis spectroscopy, FT-IR
spectroscopy and atomic force microscopy. Experimental results indicate that this method to introduce chromophore into multilayer
film can effectively prevent desorption of dye molecule. Moreover, it is found that dendrimer can inhibit the aggregation
of fluorophore in film using fluorescence spectroscopy. Increase of dendrimer’s generation can enhance fluorescence intensity
of each fluorophore. This provides a new approach to design luminescent thin film. |
