Claim Text:
1. A compound having general formula (I) or a mixture of compounds having general formula (I): wherein: X represents a heteroatom selected from the group consisting of oxygen (O), sulfur (S), selenium (Se), and tellurium (Te); R1, R2, R3 and R4, the same or different from each other, represent a hydrogen atom; or they represent a halogen atom selected from the group consisting of fluorine, chlorine, and bromine; or they are selected from the group consisting of linear or branched C1-C20 alkyl groups, saturated or unsaturated, optionally containing heteroatoms, aryl groups optionally substituted, heteroaryl groups optionally substituted, cycloalkyl groups optionally substituted, heterocyclic groups optionally substituted, trialkyl- or triaryl-silane groups, dialkyl- or diaryl-amine groups, dialkyl- or diaryl-phosphine groups, alkoxyl or aryloxyl groups, thioalkoxyl or thioaryloxyl groups, and cyano groups; or they are selected from the benzodithiophene groups consisting of general formula (II) and (III): wherein: Y, Z, W, P, Q and T, each independently, represent a sulfur atom (S), with the proviso that: at least one of P, Q and T and at least one of W, Z and Y, is a sulfur atom (S); and in general formula (III), Q and Z do not contemporaneously represent a sulfur atom (S); the remaining Y, Z, W, P, Q and T, represent a group —C—R9, —C—R10, —C—R11, —C—R12, so that the sum of the double carbon-carbon (C═C) bonds present in the two thiophene rings and in the benzene ring is equal to 5; R5, R6, R7, R8, R9, R10, R11 and R12, the same or different from each other, represent a hydrogen atom; or they represent a halogen atom selected from the group consisting of fluorine, chlorine and bromine; or they are selected from the group consisting of linear or branched C1-C20 alkyl groups, saturated or unsaturated, optionally containing heteroatoms, aryl groups optionally substituted, heteroaryl groups optionally substituted, cycloalkyl groups optionally substituted, heterocyclic groups, optionally substituted, trialkyl- or triaryl-silane groups, dialkyl- or diaryl-amine groups, dialkyl- or diaryl-phosphine groups, alkoxyl or aryloxyl groups, thioalkoxyl or thioaryloxyl groups, and cyano groups; with the proviso that, in the case of R1 and R4, when the benzodithiophene group of general formula (II) or general formula (III) is present one of Q and Z represents the group —CH; or R5 and R6, can be optionally bound to each other so as to form, together with the other atoms to which they are bound, a cycle containing from 3 to 12 carbon atoms, saturated, unsaturated, or aromatic, optionally substituted with linear or branched C1-C20 alkyl groups, saturated or unsaturated, optionally containing heteroatoms, aryl groups optionally substituted, heteroaryl groups optionally substituted, cycloalkyl groups, optionally substituted, heterocyclic groups, optionally substituted, trialkyl- or triaryl-silane groups, dialkyl- or diaryl-amine groups, dialkyl- or diaryl-phosphine groups, alkoxyl or aryloxyl groups, thioalkoxyl or thioaryloxyl groups, cyano groups, said cycle optionally containing heteroatoms selected from the group consisting of oxygen, sulfur, nitrogen, silicon, phosphorous, and selenium; or R1 and R2, R2 and R3, R3 and R4, can be optionally bound to each other so as to form, together with the other atoms to which they are bound, a cycle containing from 3 to 12 carbon atoms, saturated, unsaturated or aromatic, optionally substituted with linear or branched C1-C20 alkyl groups, optionally containing heteroatoms, aryl groups optionally substituted, heteroaryl groups optionally substituted, cycloalkyl groups optionally substituted, heterocyclic groups optionally substituted, trialkyl- or triaryl-silane groups, dialkyl- or diaryl-amine groups, dialkyl- or diaryl-phosphine groups, alkoxyl or aryloxyl groups, thioalkoxyl or thioaryloxyl groups, cyano groups, said cycle optionally containing heteroatoms selected from the group consisting of oxygen, sulfur, nitrogen, silicon, phosphorous, and selenium; with the proviso that at least two of R1, R2, R3 and R4 are selected from the benzodithiophene groups consisting of general formula (II) and (III).
