Abstract

For applications in the fields of organic electronics and photonics, disclosed are fluorescent charge-transfer compounds emitting in the visible spectral range from blue to red, including a triarylamine moiety, an electron-withdrawing group and at least two photopolymerizable groups. Also disclosed is a method for manufacturing a film-forming and photo-crosslinkable composition including at least one compound of the invention and its use as a precursor of a photocrosslinked emissive layer.
