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