wherein:
R is a substituted or unsubstituted aromatic group, a substituted or unsubstituted heteroaromatic group or a substituted vinyl group;
Ar is a condensed aromatic group;
X¹ and Y¹ are not the same and each is a hydrogen atom or a hydroxyl group, or together represent an oxygen atom which forms a carbonyl group together with the carbon atom to which X¹ and Y¹ are attached; and
X² and Y² are not the same and each is a hydrogen atom or a hydroxyl group, or together represent an oxygen atom which forms a carbonyl group together with the carbon atom to which X² and Y² are attached, or an enantiomer thereof.
