Abstract:

Novel compounds including at least two donor groups G.sup.D and at least two acceptor groups G.sup.A are disclosed. In these compounds, each donor group G.sup.D and acceptor group G.sup.A can be the same or different; any pair of donor groups G.sup.D is separated by at least one acceptor group G.sup.A; any pair of acceptor groups G.sup.A is separated by at least one donor group G.sup.D; and the total number of the donor groups G.sup.D is equal to the total number of the acceptor groups G.sup.A. Organic light emitting devices, consumer products, formulations, and chemical structures containing the compounds are also disclosed.
