The invention provides photopolymerisable or photocrosslinkable reactive mesogen for forming a hole- transporting or light emitting polymer network, said mesogen having the structure (III) wherein M is a chromophoric aromatic or heterocyclic moiety; A 1 and A 2 are carbazole groups substituted in the 3-position of the carbazole ring, and may be the same or different; S 1 and S 2 are spacers, and may be the same or different; B 1 and B 2 are polymerisable groups, and may be the same or different; and m and n are independently integers from 1 to 10. The invention also provides a material for forming a light emitting or charge transporting polymer network comprising the photopolymerisable or photocrosslinkable reactive mesogen, a charge transporting or light emitting polymer network which is obtained by polymerisation or crosslinking of the mesogen, a process for the preparation of the polymer via photopolymerisation or photocrosslinking of suitable end-groups of the mesogen, a device comprising a polymer layer formed from the charge transporting or light emitting polymer network, a process for applying a charge transporting or light emitting polymer network to a surface and a backlight or display comprising a charge transporting or light emitting polymer network. |
