    摘要： An organic vertical cavity laser light producing device includes a bottom dielectric stack reflective to light over a predetermined range of wavelengths; an organic active region for producing laser light, and having an organic active region including emissive material; and a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths. Pump-beam light is transmitted and introduced into the organic active region through at least one of the dielectric stacks. The organic active region includes one or more periodic gain region(s) and organic spacer layers disposed on either side of the periodic gain region(s) and arranged so that the periodic gain region(s) is aligned with the antinodes of the device's standing wave electromagnetic field, and wherein the spacer layers are substantially transparent to the laser light.

    摘要： An organic light-emitting device (OLED) includes an anode, a cathode, and a light-emitting layer disposed between the anode and the cathode, wherein the light-emitting layer includes a dominant host and a dopant. The device also includes an electron-transporting layer disposed in direct contact with the light-emitting layer on the cathode side, wherein the electron-transporting layer includes an electron-transporting material having the same chromophore as that of the dominant host in the light-emitting layer, wherein the electron-transporting material constitutes more than 50% by volume of the electron-transporting layer, and wherein the electron-transporting material has a greater reduction potential than that of the dominant host in the light-emitting layer.

    摘要： A process for forming an unsymmetric anthracene compound comprises a first step of forming a 9-perfluoroalkylsulfonate derivative of anthrone by reacting the anthrone with a perfluoroalkyl sulfonating agent, followed by a second step of contacting the reaction product with an aryl or heteroaryl boronic acid, ester or anhydride, and a palladium catalyst for a period of time sufficient to form an unsymmetric anthracene compound having at least one 9-position aromatic substituent.
