Features of Relationship Between Rheological and Photogeneration Characteristics of PEPC+C60 Composites
93–106 (2024)

PACS numbers: 61.43.Er, 65.60.+a, 68.35.bm, 73.50.Pz, 78.40.Me, 82.35.Np, 83.60.-a

The process of photogeneration of charges and the temperature of the transition to the viscous-flow state (Tv) in thin films of polyepoxypropylcarbazole PEPC–C60 composites fabricated by means of toluene-solution casting in strong external electric fields are investigated. Consistent and correlated changes in the temperature of the transition of the sample material to viscous-flow state (Tv) and in the effective temperature of the quantum yield of photogeneration (T0) are found out. As shown, the difference between Tv and T0 for the PEPC–C60 composites does not exceed 10% of these values, when the concentration of C60 fullerene changes. This indicates changes in the molecular structure and, consequently, dielectric constant in the vicinity of the centre of photogeneration of electric-charge carriers

KEY WORDS: amorphous molecular semiconductor, fullerene, photogeneration, electric charge, current density
