Abstract
A compound formula (I): wherein: Ar1 is a monocyclic or fused polycyclic group which, together with the rings it is fused to, forms a fused heteroaromatic group; Y is O, S or NR55, wherein R55 is H or a C1-30 hydrocarbyl group; X is O or S; R1 in each occurrence is independently H or a substituent with the proviso that at least one R1 is an electron-withdrawing group; R2 in each occurrence is independently H or a substituent; L is a direct bond or, together with R2, forms an unsubstituted or substituted 5- or 6-membered aromatic or heteroaromatic ring; and A1 in each occurrence is an electron-accepting group.
