Abstract
A photoconductive layer embodies the combination of an organic photoconductive donor compound, such as poly(N-vinyl) carbazole and derivatives thereof, and an acceptor-sensitizer compound having the general formula ##STR1## in which M is a metal such as boron, aluminum, gallium, indium and thallium, X and Y are oxygen sulphur, nitrogen, phosphorus, antimony or selenium, Z.sub.1 and Z.sub.2 are halogen, or substituted or unsubstituted alkyl, alkaryl or heterocyclic groups, R.sub.1 and R.sub.2 are substituted or unsubstituted aryl, alkaryl, alkyl or alicyclic groups, and n is 2 or 3.
Claims23
A composition for the preparation of photoconductive layers comprising the combination of an organic photoconductive donor and an acceptor-sensitizer compound having the general formula ##STR24## in which M is a metal or metalloid selected from the group consisting of aluminum, gallium, indium, thalium and boron, X and Y are groups selected from the group consisting of sulphur, nitrogen, phosphorus, antimony, selenium and oxygen, Z.sub.1 and Z.sub.2 are selected from the group consisting of a halogen and substituted and unsubstituted alkyl, alkaryl and heterocyclic groups selected from the groups consisting of furyl, pyrryl, idoyl, pyrimidyl, pyridyl and furfuryl, R.sub.1 and R.sub.2 are groups selected from the group consisting of substituted and unsubstituted aryl, alkaryl, alkyl and alicyclic groups, n is a number of 1 or 2, in which the composition used to form the layer contains the component in an amount within the range of 1-10% by weight, when in solution and 2-25% by weight, when in suspension.
A composition for the preparation of photoconductive layers comprising the combination of an organic photoconductive donor and acceptor-sensitizer compound having the general formula ##STR25## in which the composition used to form the layer contains the components in an amount within the range of 1-10% by weight, when in solution, and 2-25% by weight, when in suspension.
A composition for the preparation of photoconductive layers comprising the combination of an organic photoconductive donor and an acceptor-sensitizer compound having the general formula ##STR26## in which the composition used to form the layer contains the components in an amount within the range of 1-10% by weight, when in solution, and 2-25% by weight, when in suspension.
