摘要:
The invention relates to a process for creating nanometric structures by self-assembly of diblock copolymers, one of the blocks of which is obtained by (co)-polymerization of at least one cyclic entity corresponding to formula (I) and the other block of which is obtained by (co)-polymerization of at least one vinylaromatic monomer. (I) = where X=Si(R1,R2); Ge(R1,R2) Z=Si(R3,R4); Ge(R3,R4); O; S; C(R3,R4) Y=O; S; C(R5,R6) T=O; S; C(R7,R8) R1,R2,R3,R4,R5,R6,R7 and R8 are chosen from hydrogen, linear, branched or cyclic alkyl groups, with or without heteroatom, and aromatic groups with or without heteroatom.

The present invention relates to a composition including a graft copolymer, consisting of: a linear trunk (1) including at least one non-aromatic vinyl polymer or an unsaturated polyolefin; and at least two grafts (2) attached to said trunk via a chemical bond, each graft consisting of a conjugated polymer, characterized in that said composition further includes: fullerenes and a conjugated polymer; or carbon and/or graphene nanotubes. The invention also relates to a photovoltaic module incorporating such a composition, and to the use of said composition for the same purposes. Finally, the invention relates to methods for synthesizing the molecules forming all or part of the composition of the invention.
