The invention relates to organic semiconductive polymers comprising a new backbone system, monomers for the preparation of such polymers, methods for the preparation of such polymers and the use of such polymers in organic optoelectronic devices.

Aryl-substituted polyindenofluorenes for use in organic electroluminiscent devices

An oligomer or polymer comprising a first repeat unit and a second repeat unit that may be the same or different, the first repeat unit having formula (I): wherein each E independently represents optionally substituted nitrogen or optionally substituted phosphorus, with the proviso that at least one E is optionally substituted phosphorus; each Ar, Arand Aris the same or different and independently represents an optionally substituted aryl or heteroaryl; n is 0-3; and in the case of unsubstituted nitrogen and phosphorus, the second repeat unit is directly conjugated to the first repeat unit. 

Oligomer and polymer comprising triphenyl phosphine units

The invention relates to optical devices comprising a substrate and at least one semiconductive polymer supported by said substrate, wherein said semiconductive polymer is a copolymer in which one of the repeat units is a group of formula (I) or a homopolymer in which the repeat unit is a group of formula (I):wherein: A and B are the same or different and each comprises wholly or partially an aryl moiety or a heteroaryl moiety, said moiety in A being fused to the bond a-b and said moiety in B being fused to the bond c-d, and X is a linking unit, X being such that there is a torsion angle of at least 5&#xb0; between the bond a-b and the bond c-d about the bond b-d. The invention also relates to semiconductive polymers, monomers for preparing same, and methods for preparing random statistical conjugated polymers.
