A compound of the formula:
in which:
m and n are 0 or integers selected from 1 to 5 such that (m + n) is at least 2,
R¹ is a halogen atom,
R² to R⁷ are independently selected from the group consisting of hydrogen, alkyl groups of up to 6 carbon atoms; aryl groups of up to 20 carbon atoms; halogen; or any two of R² to R⁷ on adjacent carbon atoms may comprise the necessary atoms to complete a 5- or 6-membered carbocyclic or heterocyclic ring; at least one of R² to R⁷ being other than hydrogen;
each R⁸ independently represents a substituent of up to 20 carbon atoms selected from the group consisting of optionally substituted acyclic hydrocarbon groups; alkaryl groups; and aryl groups;
each Y is independently selected from the group consisting of S, Se, C=C and CR⁹R¹⁰ in which R⁹ and R¹⁰ are independently represent a substituted or non-substituted, aliphatic groups of up to 20 carbon atoms, or R⁹ and R¹° together represent the necessary atoms to complete a 5- or 6-membered carbocyclic ring,
each Z independently represents one or more substituents selected from the group consisting of hydrogen, halogen, nitro, cyano, optionally substituted alkylsulphonyl of up to 12 carbon atoms, optionally substituted arylsulphonyl of up to 12 carbon atoms and optionally substituted arylcarbonyl of up to 12 carbon atoms, and
X⁻ represents an anion which may optionally be incorporated with one R⁸ group to form an internal salt.
