Abstract

Thiophene oligomers which are excitable in the visible and ultraviolet region and each having at least one functional group able to form a covalent bond with organic and/or biological molecules, so as not to alter either the fluorescence properties of the oligomers or the biological activity of the bound molecules, and their use as fluorescent markers in analysis techniques.
