Indacen-4-one derivative having general formula (I) in which: - W and W1, which are the same or different, preferably the same, represent an oxygen atom; a sulfur atom; an N-R3 group in which R3 represents a hydrogen atom, or is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups; - Z and Y, which are the same or different, preferably the same, represent a nitrogen atom; or a C-R4 group in which R4 represents a hydrogen atom, or is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups, optionally substituted heteroaryl groups, linear or branched C1-C20, preferably C2-C10, alkoxyl groups, R5-O-[CH2-CH2-O]n- polyethyleneoxyl groups in which R5 is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, and n is an integer ranging from 1 to 4; -R6-OR7 groups in which R6 is selected from linear or branched C1-C20, preferably C2-C10, alkylene groups and R7 represents a hydrogen atom or is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, or is selected from R5-[-OCH2-CH2-]n- polyethyleneoxyl groups in which R5 has the same meanings as above reported and n is an integer ranging from 1 to 4, -COR8 groups in which R8 is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, -COOR9 groups in which R9 is selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, or represent a -CHO group, or a cyano group (-CN); - R1 and R2, which are the same or different, preferably the same, are selected from linear or branched C1-C20, preferably C2-C10, alkyl groups, optionally substituted cycloalkyl groups, optionally substituted aryl groups, optionally substituted heteroaryl groups, linear or branched C1-C20, preferably C2-C10, alkoxyl groups, R5-O-[CH2-CH2-O]n- polyethyleneoxyl groups in which R5 has the same meanings as above reported and n is an integer ranging from 1 to 4, -R6-OR7 groups in which R6 and R7 have the same meanings as above reported, -COR8 groups in which R8 has the same meanings as above reported, -COOR9 groups in which R9 has the same meanings as above reported, or represent a -CHO group, or a cyano group (-CN). Said indacen-4-one derivative may advantageously be used in the synthesis of electron-donor polymers, said polymers being a further object of the present invention. Said polymers may advantageously be used in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on either a rigid or flexible support. |
