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 ¹H‐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.
