Hole transport in 1,1-bis(di-4-tolylaminophenyl)cyclohexane-doped copolymers

Hole mobilities have been measured in 1,1-bis(di-4-tolylaminophenyl)cyclohexane (TAPC) doped in a series of segmented thermoplastic copolymers. The mobilities are unexpectedly high, exceeding values obtained with TAPC-doped poly(styrene) by as much as 2 orders of magnitude. The results show that the...

Description
Summary:Hole mobilities have been measured in 1,1-bis(di-4-tolylaminophenyl)cyclohexane (TAPC) doped in a series of segmented thermoplastic copolymers. The mobilities are unexpectedly high, exceeding values obtained with TAPC-doped poly(styrene) by as much as 2 orders of magnitude. The results show that the enhancement in mobilities is due to an increase in the prefactor mobilities. The activation energies are not affected by changes in the polymer host. The enhancement is attributed to the preferential segregation of the TAPC into the styrene phase of the copolymers.
