  • Photosensitive azobenzene derivative
    Patent number: 9126899
    Abstract: The present invention addresses the problem of providing with a simple production process and with high efficiency a new photosensitive azobenzene derivative which is capable of freely controlling phase transition by photostimulation, and the problem is solved by using an azobenzene derivative represented by general formula (1). (1) (In the formula, R1 and R6 are independently an alkoxyl group having 6-18 carbon atoms, R2-R5 and R7-R10 are independently a hydrogen atom or an alkyl group having 1-4 carbon atoms which may have branches, provided that not all of R2-R5 and R7-R10 are hydrogen).
    Type: Grant

  • Photo-responsive liquid crystalline compound and its applications
    Patent number: 8933208
    Abstract: The purpose of the present invention is to provide novel liquid crystalline compounds that are capable of inducing phase transition by a light stimulus and are useful in the display, optoelectronics, and photonics field. The present invention relates to the liquid crystalline compounds represented by general formula (1): wherein R1, R2 and R3 are independently selected from the group consisting of hydrogen, alkyl, alkoxyl, alkoxycarbonyl, alkoxycarbonyloxy, alkanoyl, alkanoyloxy, alkoxyphenyl, and N-alkylaminocarbonyl, and n is an integer.
