This invention is directed to substituted piperazine compounds of formula (I) and their pharmaceutically acceptable salts which are useful as antithrombotic agents by inhibiting plasminogen activator inhibitor-1 (PAI-1). In addition, the present invention relates to pharmaceutical compositions and their pharmaceutically acceptable salts, containing the substituted piperazine compounds, derivatives of the substituted piperazine compounds, and methods of using the compounds to treat disease-states characterized by thrombotic activity.
ORGANIC LIGHT-EMITTING DEVICE
An organic light-emitting device includes: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer, wherein the organic layer includes a first compound represented by Formula 1 and a second compound represented by Formula 2:
An organic light-emitting device including a first electrode, a second electrode, and an organic layer between the first electrode and the second electrode and including an emission layer; wherein the organic layer includes a host first compound represented by Formula 1 and a fluorescent dopant second compound represented by Formula 2:
When the compound represented by Formula 1 includes a condensed cyclic substituent and the compound represented by Formula 2 includes a condensed cyclic core, the organic light-emitting device may have improved thermal stability, a lower driving voltage, and higher efficiency.
