Polyester dendrimers bearing carbazole units at their peripheries were synthesized by attaching 3,5‐bis[4‐(9‐carbazolyl)butoxy]benzoic acid to the peripherical phenoxy groups. The phenoxy‐terminated polyester dendrimers were synthesized by hydrogenation of the corresponding benzyloxy‐terminated polyester dendrimers. The structure of the synthesized compounds was confirmed with IR, 1 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.
