  • Publication number: 20140284578
    Abstract: An organic compound having a low HOMO level and a high hole-transport property is provided. The organic compound is represented by Formula (G1), where Ar1 represents a substituted or unsubstituted fluorenyl group, Ar2 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and A1 represents any one of a substituted or unsubstituted dibenzofuranyl group and a substituted or unsubstituted dibenzothiophenyl group. The low HOMO level and the high hole-transport property of the organic compound allow the formation of an exciplex with another organic compound, which leads to a highly efficient light-emitting element in the presence of a phosphorescent compound due to the effective overlapping between the emission of the exciplex and the longest absorption band of the phosphorescent compound.

  • Patent number: 8755494
    Abstract: An audio indication of a message recipient is received from a user who desires that a message be sent to the message recipient. The audio indication is analyzed to determine the recipient and searching an electronic database for an account of the recipient. Information is retrieved from the electronic account. The retrieved information indicates at one or more modes of message delivery to the recipient. An audio guide for the user based is constructed upon the retrieved information. The audio guide includes one or more audio prompts that are entirely customizable and not based upon a predetermined pattern. The user is sequentially prompted with the audio prompts to select at least one of the modes of message delivery. The message is constructed and sent to the recipient according to the selected mode of message delivery.
