in which:
Q represents a dipole comprising at least one nitrogen atom;
A represents an arenediyl ring, optionally substituted by one or more hydrocarbon-based chains, which are identical or different, independent of one another, and are optionally substituted or interrupted by one or more heteroatoms;
E represents a divalent hydrocarbon-based bonding group which may optionally contain one or more heteroatoms;
R1, R2 and R3 represent, independently of one another, a hydrogen atom or a hydrocarbon-based chain which is optionally substituted or interrupted by one or more heteroatoms; and
n is an integer having a value greater than or equal to 1.
