Methods for producing organic light emitting diode (OLED) materials

摘要

Methods of producing OLED materials containing fluorene ring systems in which two alkyl substituents at the 9-position of fluorene ring are alkyl substituted through key intermediates generically represented by the formula: where X represents a substituent that increases the acidity of the hydrogen atoms on the adjoining methylene group (which is immediately adjacent the fluorene ring systems 9 -position).;

主权项

1. A method of producing fluorene OLED materials, the method comprising the steps of:
(a) deprotonation and alkylation of a compound of Formula 1:to produce a compound of Formula 7: (b) deprotonation and alkylation of the compound of Formula 7 to produce an OLED material of Formula 13: where X represents 1.3-benzo[d]thiazol-2-yl, wherein the deprotonation is with an alkyl lithium base, wherein the alkylation is with an α,ω-dihaloalkane, and wherein n and m are independently of one another 2 or 3.
