Abstract
The oligomer containing 9-[2-(9H-carbazol-9-yl)cyclobutyl]-9H-carbazole moiety in the main chain and its model compound were synthesized by Wittig reaction. Both compounds form glasses with glass transition temperatures of 254°C and 135°C respectively. The optical and photoelectrical properties of the compounds were studied. The hole drift mobilities observed in the film of the oligomer by the time of flight technique were in the range of 2.10 -6 - 7.10 -6 cm 2 /(V.s) at an applied electric field ranging from 5.8.10 4 to 2.7.10 5 V/cm.
