  • Gelator and organogel
    Patent number: 9744512
    Abstract: There is provided a novel gelator which enables formation of gel by a simpler technique. A gelator including two or more alkylamide compounds of General Formula [I]: (where R1 is a C1-30 aliphatic group optionally having a substituent) or two or more alkylurea compounds of General Formula [II]: (where R2 is a C1-30 aliphatic group optionally having a substituent), wherein the gelator forms a gel exhibiting thixotropic properties.

  • Vinyl polymer and organic electroluminescent device
    Patent number: 7160634
    Abstract: An organic electroluminescent device having an organic layer between a pair of electrodes. The organic layer (in particular, a hole-transporting layer) has a polymer of a vinyl compound represented by the following formula (1): wherein R1 and R2 are the same or different, each representing a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group. The glass transition temperature of the polymer is about 200 to 250° C., and the polymer has high heat-resistance. Thus, the use of the polymer improves heat resistance of an organic EL device.
