    摘要: The present invention relates to a catalyst having general formula (I): M[SbOn(OH)2(3-n)]x  (I) wherein: M represents at least one cation of an element selected from earth-alkaline metals belonging to groups IIA, IIIA, VA, or transition metals belonging to groups IIB, IIIB, VB or VIIIB; n represents an integer between 0 and 2 and x is an integer between 2 and 5. The invention also relates to a process for the synthesis of polyol polyethers which uses a catalyst having general formula (I).

    摘要: The present invention relates to copolymers for solar cells based on acridonic units comprising: a monomeric unit (A) having general formula (I) wherein X is S or Se, Y is 0, S or NR′ and R, R′, the same or different, are C4-C24 alkyl groups, aryl groups optionally substituted with other functional groups, acyl groups or thioacyl groups; at least one monomer unit (B) having general formula (II) wherein Z is 0, S, Se or N—R″, wherein R″ is a C4-C24 alkyl group, an aryl group optionally substituted with other functional groups, an acyl group or thioacyl group, said monomeric unit (B) being connected to any position available of a hetero-aromatic side ring of the unit (A) through one of the two positions indicated by the dashed lines in general formula (II). Photovoltaic devices comprising said alternating π-conjugated polymers are also described.
