A conjugated or partially conjugated polymer including a structural unit of Formula (I); where T is an aryl or heteroaryl group that may be substituted or unsubstituted, or a C1-C24 alkyl group; R1 is alkyl, alkoxy, aryl group, cyano, or F; and a and b are independently selected from 1, 2 or 3. In addition, a composition of Formula (IV); wherein X is a halogen or a boronate group. 

Biscarbazol-9-yl-substituted triarylamine-containing polymers and electronic devices

A halogenated bisdiarylaminopolycyclic aromatic compound, polymers made therefrom, and polymeric light emitting diode devices using the polymers are described. The halogenated compound is represented by formula (I), wherein Ar and Ar' are each independently substituted or unsubstituted aryl groups and Z is a polycyclic arylene group, wherein at least one of the Ar&#x2032; groups is a haloaryl group. Devices using polymers prepared from the halogenated compound exhibit improved performance and longer lifetime, presumably as a result of the presence of the geometrically constrained diarylaminopolycyclic aromatic groups in the polymer backbone. 

Halogenated bisdiarylaminopolycyclic aromatic compounds and polymers thereof

The present invention relates to a composition comprising a blend of a luminescent polymer and a low molecular weight (&#x3c;5000 amu) viscosity modifier, which has an emission maximum in the range of 350-480 nm, contains no exocyclic double bonds, and modifies the viscosity of the polymer without substantially altering emissive properties of the neat polymer. Modification of viscosity without concomitant modification of emissive properties is desirable where the polymer is already tuned to emit at the desired wavelength.

Blend of viscosity modifier and luminescent compound

A method for preparing a composition of the formulain a yield greater than 50% where Ris C 1-20 comprising the steps of combining fluorene or dibromo flourene, an excess of alkali metal hydroxide and a halogenated alkyl in the presence of a phase transfer catalyst but in the absence of a polar aprotic solvent; heating the combination; and separating the dialkylated fluorene or dialylated dibromo fluorene. If the flourene is not brominated prior to alkylation, the dialkylated fluorene is then brominated.

Method for producing substituted fluorene monomers

A composition comprising a polymer comprising a repeat unit of Formula I:wherein Ris independently in each occurrence H, Chydrocarbyl or Chydrocarbyl containing one or more S, N, O, P or Si atoms, or both of Rtogether with the 9-carbon on the fluorene, may form a Cring structure which may contain one or more S, N, or O atoms;

Tricyclic arylamine containing polymers and electronic devices therefrom

A polymer comprising repeat units of the formula:wherein Ris independently in each occurrence Chydrocarbyl or C1-20 hydrocarbyl containing one or more heteroatoms of S, N, O, P or Si or both Rmay form, with the 9-carbon of the fluorene ring, a Cring structure containing one or more heteroatoms of S, N, or O; Ris independently in each occurrence Chydrocarbyl, Chydrocarbyloxy, Cthioether, Chydrocarbyloxycarbonyl, hydrocarbylcarbonyloxy, or cyano; a is independently in each occurrence a number from about 0 to about 1;

Fluorene-containing polymers and compounds useful in the preparation thereof

An organic block polymer useful in an electroluminescent polymer device (or in a polymer field effect transistor) that includes an emissive polymer block that is consistently conjugated along the backbone of the emissive polymer block (e.g., a copolymer of 2,7-linked 9,9 dioctyl fluorene and 4,7-linked 2,1,3 benxothiadiazole); and a positive charge carrier polymer block that is consistently conjugated along the backbone of the positive charge carrier polymer block (e.g., a copolymer of 2,7-linked 9,9 dioctyl fluorene and 4N, 4N&prime;-linked N,N&prime;-di(3-carboxomethoxyphenyl)benzidine) for transporting positive charge carriers to the emissive polymer block so that the positive charge carriers can combine with negative charge carriers to generate light.
