Abstract
Materials and a process for producing the materials are useful in electrophotographic imaging members. The materials are produced through a sol-gel process wherein a hybrid material, which may be obtained through hydrolysis and condensation, includes an inorganic glassy network, a flexible organic subunit and a functional subunit. The latter two subunits may be unitary. The materials can be easily coated for fabricating electrophotographic imaging members and the like.
Claims34
A multilayer electrophotographic imaging member, comprising at least one photoresponsive layer, wherein at least one layer of said imaging member is composed of a compound containing subunits of the formula G-D-F, wherein G is an inorganic glassy network subunit, D is a flexible organic subunit, and F is a subunit having charge transporting or generating characteristics.
An imaging member, comprising a layer of a photoresponsive compound made by a process comprising the steps of:
- a) hydrolyzing a metal alkoxide;
- b) forming a sol by adding to said metal alkoxide a functional precursor, having polymeric and photoresponsive properties, which will participate in a sol-gel reaction;
- and
- c) condensing said metal alkoxide with said functional precursor to form a gel.
An imaging member comprising a layer of a compound containing subunits of the formula G-E, wherein G is an inorganic glassy network unit and E is a functional subunit having polymeric and photoresponsive properties.
