Abstract: The invention relates to compounds having formula (I): Scaffold-[L-(Antigen)t]y (I) wherein Antigen represents at least a portion of a target antigen for modulating an immune response; wherein t is 0 or an integer of at least 1; wherein y is at least 1; wherein the number of Antigens on the Scaffold is at least 2; wherein L is a linking group or a covalent bond, wherein when L is a covalent bond, the covalent bond is a single bond attached to a sp or sp2 hybridized atom of the Scaffold and when L is a linking group, the linking group is attached to the Scaffold through a single bond attached to a sp or sp2 hybridized atom; whereby the Scaffold is sufficiently rigid to maintain the relative position of the single bonds attached to sp or sp2 hybridized atoms. Further described are compositions containing the compounds and methods of using them.

Abstract: This invention discloses a new class of bifunctional blue emitting materials for organic electroluminescent (EL) applications. These compounds contain two functionalities: an emission chromophore comprised of an anthryl group and an electron transport group. Employment of these compounds improves device efficiency and stability.

Abstract: The present invention is an organic light emitting device (OLED) comprising an anode, a cathode and a luminescent region provided between the anode and the cathode. The luminescent region comprises an electron injection and transporting zone and at least one of a hole injection and transporting zone and a mixed charge transport layer. One or both of the electron injection and transporting zone and the mixed charge transporting layer comprises an azole compound represented by formula I and/or II. The provision of the novel azole compounds of the invention as electron transport materials within an organic electroluminescent device advantageously reduces power consumption and increases power conversion efficiency within the device and as such, are suitable for a variety of display applications.
