Patent ID: 8829202

Claim:
A condensed polycyclic aromatic compound represented by the following formula (II): (wherein each of X 1 and X 2 is independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having from 1 to 20 carbon atoms, an alkenyl group having from 2 to 20 carbon atoms, an alkynyl group having from 2 to 20 carbon atoms, a substituted or unsubstituted aromatic group having from 4 to 20 carbon atoms, a ketone group having from 2 to 10 carbon atoms, an amino group having from 1 to 20 carbon atoms, an amide group having from 1 to 20 carbon atoms, an imide group having from 1 to 20 carbon atoms, a sulfide group having from 1 to 20 carbon atoms, and an alkylsilylalkynyl group having from 1 to 40 carbon atoms, and at least one of X 1 and X 2 is a halogen atom; B is a condensed ring having at least one benzene ring moiety; each Y is independently selected from chalcogens; and each of A 1 to A 4 is independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having from 1 to 20 carbon atoms, an alkenyl group having from 2 to 20 carbon atoms, an alkynyl group having from 2 to 20 carbon atoms, a substituted or unsubstituted aromatic group having from 4 to 20 carbon atoms, a ketone group having from 2 to 10 carbon atoms, an amino group having from 1 to 20 carbon atoms, an amide group having from 1 to 20 carbon atoms, an imide group having from 1 to 20 carbon atoms, a sulfide group having from 1 to 20 carbon atoms, and an alkylsilylalkynyl group having from 1 to 40 carbon atoms, and two adjacent members out of A 1 to A 4 may combine with each other to form a substituted or unsubstituted aromatic group having from 4 to 20 carbon atoms).
