Abstract
Polyester dendrimers bearing carbazole units at their peripheries were synthesized by attaching 3,5-bisl4-(9-carbazoly)butoxy]benzoic acid to the peripherical phenoxy groups. The phenoxy-terminated polyester dendrimcrs were synthesized by hydrogenation of the corresponding benzyloxy-terminated polyester dendrimers. The structure of the synthesized compounds was confirmed with IR, 'H NMR. MALDITOF MS and GPC. The reaction conditions for attaching 3,5-bis[4-(9-carbazolyl)butoxy]benzoic acid to the peripherical phenoxy groups of polyester dendrimers were studied. Fluorescence spectra studies showed that there exist strong intramolecular interactions in the carbazole dendrimer molecules.
