Synthesis and Characterization of Random Copolymers Combining Terfluorene Segments and Hole or Electron Transporting Moieties

New random copolymers having a well defined terfluorene unit with different hole or electron transporting moieties such as vinyl-carbazole (scTFPCARBZ) and side chain oxadiazole (scTFPOXD) were synthesized using the free radical polymerization technique. The synthesized materials were characterized...

Description
Summary:New random copolymers having a well defined terfluorene unit with different hole or electron transporting moieties such as vinyl-carbazole (scTFPCARBZ) and side chain oxadiazole (scTFPOXD) were synthesized using the free radical polymerization technique. The synthesized materials were characterized with a variety of spectroscopic techniques such as 1 H-NMR, gel permeation chromatography (GPC), differential scanning calorimetry (DSC), cyclic voltammetry, Fourier transform infrared spectroscopy, UV-Vis absorption and photoluminescence. All the copolymers exhibit blue light emission, while an efficient energy transfer was detected from the oxadiazole-based homopolymer to the terfluorene block both in solution and in the solid state for scTFPOXD. Finally, the influence of the photo-oxidation treatment on the optical properties of the random copolymers was examined.
