Compounds of Formula (I): Wherein: R1 and R2 are independently selected from the group consisting of optionally substituted C1-C20 alkyl, optionally substituted C3-C8 cycloalkyl, optionally substituted aromatic, and optionally substituted heteroaromatic groups or R1 and R2 together with the nitrogen atom to which they are attached comprise an optionally substituted saturated or unsaturated ring which may optionally contain further heteroatoms selected from the group consisting of O, N and S, and may optionally be further fused to one or more other rings; Ar is selected from the group consisting of optionally substituted aromatic and optionally substituted heteroaromatic groups; L is a linker which is a direct bond or is selected from the group consisting of optionally substituted C2 alkenylene and optionally substituted C2 alkynylene; T is independently selected from the group consisting of: R3, R4 and R9 are independently selected from the group consisting of hydrogen, optionally substituted C1-C10 alkyl, optionally substituted C3-C8 cycloalkyl and optionally substituted C1-C10 alkoxy groups, or a pair of groups selected from R3, R4 and R9 may together with the carbon atoms to which they are attached comprise an optionally substituted saturated or unsaturated ring which may optionally contain one or more heteroatoms selected from the group consisting of O, N and S, and may optionally be further fused to one or more other rings; R5 is selected from the group consisting of hydrogen, optionally substituted C1-C8 alkyl, optionally substituted C3-C8 cycloalkyl, and optionally substituted aromatic groups; R6 is selected from the group consisting of optionally substituted C1-C8 alkyl, optionally substituted C1-C8 perfluorinated alkyl, optionally substituted C3-C8 cycloalkyl, optionally substituted aromatic, and optionally substituted heteroaromatic groups; R7 is selected from the group consisting of optionally substituted C1-C30 alkyl wherein one or more carbon atoms of the alkyl are optionally replaced with one or more of O, S, NR8, carbonyl or thiocarbonyl; optionally substituted C3-C8 cycloalkyl; optionally substituted C2-C12 alkenyl wherein one or more carbon atoms of the alkenyl are optionally replaced with one or more of O, S, NR8, carbonyl or thiocarbonyl; optionally substituted C2-C8 alkynyl wherein one or more carbon atoms of the alkynyl are optionally replaced with one or more of O, S, NR8, carbonyl or thiocarbonyl; optionally substituted C3-C12alkoxy; optionally substituted aromatic; and optionally substituted heteroaromatic groups; wherein R8 is hydrogen or R6, and n is an integer of 1 to 10. The compounds are capable of charge transportation and have application in organic photovoltaic devices such as dye sensitised solar cells.
