An electrophotographic photoconductor is composed of an electroconductive substrate and a photoconductive layer formed thereon, the photoconductive layer includes a dipyrenylamine derivative of formula (I): ##STR1## wherein R represents an alkyl group with 1 to 12 carbon atoms, which may have a substituent, or an aryl group which may have a substituent. Novel dipyrenylamine derivatives of formula (I), in which R is -ph-(R.sup.4)n, wherein, ph is a phenyl group, R.sup.4 is hydrogen, an unsubstituted or substituted alkyl group having 1 to 12 carbon atoms, an unsubstituted or substituted alkoxyl group having 1 to 12 carbon atoms, n is an integer of 1 to 5, and when n is 2 to 5, R.sup.4 may be the same or different, which are for use in the photoconductive layer of the electrophotographic photoconductor, are synthesized.
一种电子光导感光体由电导基板和其上形成的感光层组成,感光层包括式(I)的二吡啶胺衍生物:##STR1## 其中R代表具有1至12个碳原子的烷基基团,可能具有取代基,或者是可能具有取代基的芳基基团。合成了式(I)中R为-ph-(R.sup.4)n的新型二吡啶胺衍生物,其中ph是苯基,R.sup.4是氢,具有1至12个碳原子的未取代或取代的烷基基团,具有1至12个碳原子的未取代或取代的烷氧基团,n是1至5的整数,当n为2至5时,R.sup.4可以相同也可以不同,这些衍生物用于电子光导感光体的感光层。
