  • Patent number: 8580392
    Abstract: The invention relates to an organic light-emitting diode (OLED) having an improved lifetime and improved transport of negative charge carriers. The organic light-emitting diode is based on an organic semiconductor material, in which the transport of negative charge carriers and stability with respect to reduction is achieved with triarylated Lewis acid units, in particular perarylated borane units. This leads to an improved lifetime of the emission layer which in turn increases the lifetime of the component and eliminates the need for correcting brightness during operation. Furthermore, the invention relates to organic light-emitting diodes in which the position of the emission zone in the emitter layer and the color of the emission can be influenced in a targeted manner through triarylated Lewis acids such as perarylated borane units.

  • Patent number: 8298443
    Abstract: A method for producing a polymer comprising reacting a fluoride and a monomer having a boronic acid moiety, or a salt thereof, in acidic aqueous solution and/or in an aliphatic alcohol. Polymerization occurs with the addition of an oxidizing agent. The method may further comprise the step of purification of the polymer by centrifugation with 0.5 M HCl and/or dispersion of the polymer in a solvent. The polymer has a morphology tunable by changing the solvent.

  • Patent number: 8101786
    Abstract: The reaction of halo-boron compounds (B—X compounds, compounds having one or more boron-halogen bonds) with silanes provides boranes (B—H compounds, compounds having one or more B—H bonds) and halosilanes. Inorganic hydrides, such as surface-bound silane hydrides (Si—H) react with B—X compounds to form B—H compounds and surface-bound halosilanes. The surface bound halosilanes are converted back to surface-bound silanes electrochemically. Halo-boron compounds react with stannanes (tin compounds having a Sn—H bond) to form boranes and halostannanes (tin compounds having a Sn—X bond). The halostannanes are converted back to stannanes electrochemically or by the thermolysis of Sn-formate compounds. When the halo-boron compound is BCl3, the B—H compound is B2H6, and where the reducing potential is provided electrochemically or by the thermolysis of formate.
