Abstract
The present invention discloses a novel polyheteroaromatic compound derived from 7′,7′-dimethyl-5′,7′-dihydrospiro[cyclopenta[1,2-b:5,4-b′-dithiophene-4,13′-indeno[1,2-b]acridine] core structures. The polyheteroaromatic compound can be used as organic electroluminescence materials for use in an organic electroluminescence device and electronic equipment.
