Patent ID: 7968004

Claim:
An optoelectronic device having a layer comprising a polymer having greater than 10% by weight of structural units derived from a compound of formula I wherein R 1 and R 2 are independently at each occurrence H, C 1-20 hydrocarbyl, C 1-20 hydrocarbyl containing one or more S, N, O, P or Si atoms, C 4-16 hydrocarbyl carbonyloxy, C 4-16 aryl(trialkylsiloxy) or R 1 and R 2 taken together with an intervening carbon atom form a C 5-20 hydrocarbyl ring or a C 4-20 hydrocarbyl ring containing at least one S, N or O heteroatom; R 3 and R 4 are independently at each occurrence C 1-20 hydrocarbyl, C 1-20 hydrocarbyloxy, C 1-20 thioether, C 1-20 hydrocarbylcarbonyloxy or cyano; X is independently at each occurrence halo, triflate, —B(OH) 2 , —B(OR) 2 , —BO 2 R, or a combination thereof; R is alkyl or alkylene; and a and b are independently 0 or 1.
