Styrene-based monomers with the first- and second-generation dendronized carbazoles were synthesized by a convergent strategy. Conventional free radical polymerizations were carried out to synthesize the dendronized jacketed polymers using these two monomers. The apparent molecular weights of the two polymers determined by gel permeation chromatography were 57 000 and 34 000 g/mol, respectively. The polymers had excellent thermal stability with their 5% weight loss temperatures all above 360 °C. Their photophysical properties in solutions and films were investigated. Different solvents had negligible effects on their UV−vis or photoluminescent (PL) spectra. A 10 nm blue shift of the emission peak was observed in the PL spectra of films compared with those of solutions. After the films were annealed, the emission peaks became narrower. X-ray diffraction techniques were utilized to examine the phase structures of the dendronized jacketed polymers. The first-generation polymer formed a hexatic columnar nemat...
