摘要:
Disclosed is a chiral phase-transfer catalyst having a simplified structure, which can be produced by reacting a 2,2'-dimethylenebromide-1,1'-binaphthyl derivative (which can be produced in relatively small numbers of steps) with a secondary amine (which is readily available). The catalyst is a compound represented by the formula (I) having a long-chain alkyl group R 7 in its chemical structure. The catalyst is expected to show a high stereoselectivity even in a reaction where a conventional catalyst does not show a satisfactory stereoselectivity such as an asymmetric alkylation reaction.
摘要:
A guanidine compound which has a bi-aryl skeleton represented by the following general formula (1): [wherein R , R and R each independently represents a hydrogen atom, a hydrocarbon group optionally having a substituent or a heterocyclic group optionally having a substituent, R to R each independently represents a hydrogen atom, a hydrocarbon group optionally having a substituent, a heterocyclic group optionally having a substituent or the like, and in any combination of R to R , these substituents may together bind with each other to form a ring, and X to X each represents a carbon atom or a nitrogen atom]. The above guadinine compound is useful as a catalyst for a variety of asymmetric reactions.
摘要:
A novel class of low reflectivity, high transparency, non-metallic cathodes (1) useful for a wide range of electrically active, transparent organic devices is disclosed. As a representative embodiment, the highly transparent non-metallic cathode (1) of an OLED employes a thin film of copper phthalocyanine (CuPc) (6) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85 % transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions.

As a representative embodiment, the highly transparent non-metallic cathode of an OLED employs a thin film of copper phthalocyanine (CuPc) capped with a film of low-power, radio-frequency sputtered indium-tin-oxide (ITO). The CuPc prevents damage to the underlying organic layers during the ITO sputtering process. Due to the low reflectivity of the non-metallic cathode, a non-antireflection-coated, non-metallic-cathode-containing TOLED is disclosed that is 85 % transmissive in the visible, emitting nearly identical amounts of light in the forward and back-scattered directions. The performance of the non-metallic-cathode-containing TOLED is found to be comparable to that of TOLEDs employing a more reflective and absorptive cathode consisting of a semi-transparent thin film of Mg:Ag capped with ITO. The present invention is further directed toward novel OLEDs in which the highly transparent non-metallic cathodes may be used in OLEDs comprised of a charge carrier layer containing a compound having molecules that have at least one electron transporting moiety and at least one hole transporting moiety, OLEDs comprised of an emissive layer containing an azlactone-related dopant, OLEDs comprised of an emissive layer containing a phosphorescent dopant compound, or OLEDs comprised of a hole transporting layer containing a glassy organic hole transporting material comprised of a compound having a symmetric molecular structure.
