摘要:
A polymer for use in an optical device comprising a first, optionally substituted, repeat unit of formula and a second, optionally substituted, repeat unit of formula wherein each Ar and Ar′ is the same or different and comprises an optionally substituted aryl or heteroaryl group and optionally a third, optionally substituted, repeat unit in a molar ratio of no greater than 5%, the third repeat unit having a formula —Ar—N(Ar)—Ar— and having a single nitrogen atom in its backbone.

An electroluminescent device comprising:—a first electrode for injection of positive charge carriers;—a second electrode for injection of negative charge carriers; and—an electroluminescent layer located between the first and second electrodes comprising a host material and a metal complex, wherein the host material comprises a polymer having a first repeat unit of formula (I): wherein each Ar is the same or different and independently represents an optionally substituted aryl or heteroaryl and any two Ar groups may be directly linked by a single bond.
摘要:
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 Ar1, Ar2 and Ar3 is 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.
摘要:
A process for the preparation of a conjugated poly(arylene vinylene) copolymer for use in a luminescent device, which comprises: (1) providing a precursor polymer comprising units of general formula in which Ar is substituted or unsubstituted arylene, L is a leaving group, R1 and R2 are each independently H, alkyl, alkoxy, aryl or an electron-withdrawing group, and n is an integer; (2) reacting the precursor polymer with a reactant comprising a carboxylate, an aldehyde, a ketone, a sulphonate, a thioate, a disulphide, a xanthate, an amine, a pyridine, a hydrazide, a phenoxide, an alcohol with a boiling point above 100° C., or a derivative thereof, under substitution conditions whereby a proportion of the leaving groups are substituted to form a substituted precursor copolymer comprising units of general formula in which Ar, R1, R2 and L are defined above, X is a substituent group from the reactant, l and m are independently integers; and (3) converting the substituted precursor copolymer to a conjungated poly(arylene vinylene) copolymer by elimination of the leaving groups from the substituted precursor copolymer.
