Paper Abstract

Derivatives of trinitrofluorenone, bisphenylquinone, thiopyran, oxadiazole, anthraquinone may be mentioned as electron transporting materials (ETM). Because of high crystallization speed of these materials it is difficult to prepare organic electrophotographic layers of high quality. It is a common fault of these ETM. In this work was prepared ETM with good film forming properties by reaction of 1-(2,3- epoxypropylamino)anthraquinone and 1,3-benzenedithiol. ETM bis[4-(anthraquinone-1-amino)-3-hydroxy-1-thiabutyl]- benzene was obtained this way. The drift mobility of electrons was measured by a time-of-flight method. The transient of a small charge had a fast relaxation but a characteristic kink, by which the time of transit was determined, was weakly expressed because of a strong degree of dispersion of electron transport. The drift mobility of electrons was 4.6(DOT)10-7 cm2/Vs at an electric field strength 8 (DOT) 105 V/cm and the temperature of 26 degrees Celsius. The photosensitivity of positively charged photoreceptor consisting of the lower photogenerative layer of Y-type titanyl phthalocyanine and an ETM transport layer in the spectral range 600 nm to 860 nm is as high as 80 m2J-1 to 120 m2J-1.
