Compound of formula (I) below:
- in which:
- R1 represents an alkylene group comprising from 1 to 6 carbon atoms or an —O-alkylene group comprising from 1 to 6 carbon atoms;
- R2 and R3, identical or different, are chosen from the group consisting of:
- H, NO2, ORa, SRa and NRaRb, wherein Ra and Rb, identical or different, represent H or an alkyl group comprising from 1 to 6 carbon atoms, or R2 and R3 may together form a phenyl group with the carbon atoms carrying them;
- n is 0, 1, 2 or 3;
- R4 is chosen from the group consisting of:
- NO2, ORa, SRa and NRaRb, wherein Ra and Rb are as defined above;
- R5 and R6, identical or different, represent an alkyl group comprising from 1 to 6 carbon atoms or an alkoxy group comprising from 1 to 6 carbon atoms;
- and
- R7, R8 and R9, identical or different, represent an alkyl group comprising from 2 to 6 carbon atoms or an alkoxy group comprising from 2 to 6 carbon atoms.
