A compound of formula (I)

• whereby A1 is selected from formula (II)
• wherein
• Ar1 is selected from substituted or unsubstituted C6 to C12 aryl, or substituted or unsubstituted C2 to C12 heteroaryl,
• Ar2 is selected from substituted or unsubstituted C6 to C12 aryl, substituted or unsubstituted C2 to C12 heteroaryl, or forms together with Ar1 a substituted or unsubstituted C10 to C22 aryl, or a substituted or unsubstituted C3 to C22 heteroaryl,
• and wherein the substituents on Ar1 and Ar2 are independently selected from CN, partially or perfluorinated C1 to C6 alkyl, CF3, halogen, Cl, F, or D;
