Abstract
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).
