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.

Photo-crosslinkable emissive molecular materials

Metallopolymers of formula (I) where Rand R'; and Rand R&#x2032; are independently of each other, a C-Calkyl group; X is CR3R3&#x2032; or NR4; Rand R&#x2032; are, independently of each other, as is R, a C-Calkyl group; L is a C-Calkylene group; Lnand Lnare, independently of each other, chosen from the lanthanide cations; Land Lare, independently of each other, chosen from the &#x3b1;-diketonate ligands; T is a neutral bidentate Lewis base including two coordinating nitrogen atoms; &#x2192; represents a coordination of group T via the two nitrogen atoms of T to Lnand Lnrespectively; Lnand Lnare, independently of each other, chosen from the lanthanide cations; Land Lare, independently of each other, chosen from the &#x3b2;-diketonate, picolinate or dipicolinate monoanionic ligands; 0.01&#x3c;x&#x3c;0.50; 0&#x3c;y&#x3c;0.49, with x+y=0.50.
