ALKYNYL-SUBSTITUTED INDENOFLUORENES USEFUL IN ELECTRONIC AND ELECTRO-OPTICAL DEVICES

摘要

The present invention relates to the synthesis of fully conjugated pentacene-like indeno[1,2-b]fluorenes of formula 1 and 2 (shown below) comprising at least two alkynyl or substituted alkynyl moieties wherein R1 - R12 are as defined herein. Compounds of the present application were found to have greater stability compared to pentacene and are useful in electronic and electro-optical devices.
