Compounds which are useful as sensitisers of photoconductors, having the general formula:
in which:
like symbols represent identical substituents, at least 4 of R1 to R9 represent hydrogen atoms and the remaining R1 to R9 pairs of groups independently represent:
(i) hydrogen, an alkyl group having from 1 to 18 carbon atoms, a substituted alkyl group or an aryl or substituted aryl group,
(ii) a halogen atom, a cyano group, a carboxy or alkoxycarbonyl group, a hydroxy group, an alkoxy group, a nitro group or a sulphonic acid group, providing that not more than two such groups (ii) are present in each ring,
(iii) an acylamino group, a secondary acylamino group, or a tertiary amino group, in which the pendant substituent groups on the nitrogen atom are alkyl, aryl or aralkyl, providing not more than two sush groups (iii) may be present in each benzocarbazole ring, and (iv) any two groups R1 to R9 on adjacent carbon atoms in a ring may represent the necessary atoms to complete a fused alicyclic, aromatic or heterocyclic ring, R10 represents an alkyl or substituted alkyl group, an aralkyl group, or an aryl or substituted aryl group,
Ar represents a heteroaromatic nucleus eontaining 5 or 6 members in the ring at least one of which is O, N or S, or an aromatic ring of the formula:
in which:
R11 to R16 independently represent a hydrogen or halogen atom, an alkyl or substituted alkyl, an aryl or substituted aryl, hydroxy, alkoxy or aryloxy group,
one of R" to R15 may additionally represent an aldehyde or acetyl group or a dialkylamino group,
up to two of R" to R15 may additionally represent a cyano, carboxy, alkoxy carbonyl, sulphonic acid or nitro group, and
any two adjacent R" to R15 groups may represent the necessary atoms to complete a fused alicyclic, aromatic or heterocyclic ring, and
X represents an anion.
