摘要

Two generations of carboxyl-terminated poly (aryl ether) dendrimers bearing 9,10-dipnenyIanthraeene cores are designed and synthesized. Alternating deposition of two dendrimers and poly(4-vinylpyridine) is studied with DV-Vis spectroscopy, FT-IR spectroscopy and atomic force microscopy. Experimental results indicate that this method to introduce chromophor into multilayer film can effectively prevent desorption of dye molecule. Moreover, it is found that dendrimer can inhibit the aggregation of ftaorophore 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.
