摘要:
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.

摘要:
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′ 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.
摘要:
A conjugated or partially conjugated polymer comprising a structural unit of Formula I: I Wherein Ar1 is an aromatic group which contains one or more heteroatoms, or an aromatic group which comprises one or more fused aromatic or non-aromatic rings, said aromatic group may be substituted or unsubstituted; and R1 is alkyl, alkoxy, and aryl group, cyano, or F.
摘要:
A halogenated aromatic monomer-metal complex useful for preparing a polymer for electronic devices such as a light-emitting diode (LED) device is described. The aromatic monomer-metal complex is designed to include a linking group that disrupts conjugation, thereby advantageously reducing or preventing electron delocalization between the aromatic monomer fragment and the metal complex fragment. Disruption of conjugation is often desirable to preserve the phosphorescent emission properties of the metal complex in a polymer formed from the aromatic monomer-metal complex. The resultant conjugated electroluminescent polymer has precisely controlled metal complexation and electronic properties that are substantially or completely independent of those of the polymer backbone.

摘要:
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′-linked N,N′-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.
摘要:
A method and system is provided for emulating individual JTAG devices in a multiple device boundary scan chain. The method includes coupling an emulator to the scan chain, and obtaining the topology of the scan chain. One device within the scan chain is then selected, and at least one other device within the scan chain is placed into bypass mode. Emulation instructions are sent to the scan chain, so that the emulation instructions bypass the at least one other device and are executed by the one device.
