Abstract:
A polymer compound in which coumarin or a derivative thereof is bonded to at least one terminal of a skeletal polymer. A flow property of the polymer compound is reversibly changeable from a first state to a second state by irradiation with light at a first wavelength and from the second state to the first state by irradiation with light at a second wavelength different from the first wavelength.
Abstract:
A liquid fuel containing an ionic microgel is provided. A fuel cell having an anode for oxidizing the liquid fuel, a cathode for reducing an oxidizing agent, and an electrolyte film sandwiched between the anode and the cathode is provided.
