ABSTRACT:
The invention relates to novel 2-(N,N-di(het)arylamino)-thiophene derivatives of formula (I), wherein R1, R2, R3, R4and R5are, independently each of other, each a monofunctional (het)aryl system and wherein R1can also be a bifunctional (het)arylene system, R3can also be a group R8, except when R1is a bifunctional (het)arylene system, R8representing chemical bond or a bifunctional (het)arylene system, R4can also mean R10, R10representing a chemical bond or a bifunctional (het)arylene system, or R4can be one of the following groups (II) and (III), R9representing a chemical bond or a bifunctional (het)arylene system and R5can also be H or (IV).
