摘要： PROBLEM TO BE SOLVED: To obtain a polymeric material for optical communication having higher heat resistance than polymethyl methacrylate and being excellent in the easiness of controlling a refractive index by selecting a polymeric material containing a compound having a specified structure. SOLUTION: This material contains a compound represented by formula I and having a weight-average molecular weight of 10,000-1,000,000, has more excellent heat resistance than polymethyl methacrylate, and is exemplified by a compound represented by e.g. formula II or III. A compound represented by formula I is obtained by heating under agitation a solution prepared by dissolving polymethyl methacrylate and 2,2,2-trifluoroethylamine in a solvent such as N-methylpyrrolidone to form a reaction solution, adding the reaction solution dropwise to water to form a precipitate, and separating it by filtration. A compound represented by formula III is obtained by dissolving polymethyl methacrylate and a methylamine/methanol solution in a solvent such as N-methylpyrrolidone, heating the mixture under agitation to form a reaction solution, and adding the reaction solution dropwise to water to form a precipitate. In the formulae, R is an alkyl or a phenyl; X is hydrogen, deuterium or a halogen; and n is the degree of polymerization.

摘要： PURPOSE:To provide an odor sensor having the uniform response characteristics. CONSTITUTION:On an alumina ceramic substrate 11, on which comb-shaped electrodes 13 are formed, copper phthalocyanine undergoes vacuum deposition, and an induction film 15 is formed. An element, wherein the induction film 15 is formed, undergoes heat treatment for 1b minutes in a constant temperature oven at the temperature of 150 deg.C. Then, the element immediately after the heat treatment is quickly moved into a hermetically sealed container made of glass, wherein iodine powder is contained and left alone for 40 minutes. Then, the organic induction film 15, which has undergone chemical doping, is left alone in the air for 10 hours or longer. Thus, a part of the iodine doped with the induction film 15 is naturally desorbed. Finally, the state, wherein the constant amount of the iodine is chemically adsorbed into the induction film, is obtained.

摘要： PURPOSE:To transmit information between liposome by means of chemical substances by providing on a substrate a first liposome having the chemical substances therein and optical reactivity and a second liposome having film potential sensitive substances therein and fluorescent emission. CONSTITUTION:On a polystyrene substrate 42 are provided a first optical reactive liposome 56 including chemical substances and a second fluorescent liposome including film potential sensitive substances. The first liposome 56 is composed of the mixed lipids of optical resoluble phospholipid and natural phospholipid constituting its lipid bimolecular membrane. When the bio element is irradiated by light, any chemical substance will be discharged from the liposome 56 through optical resolving and be taken in the liposome 58, resulting in changing the film potential of liposome. There will occur any changes in fluorescent intensity of the liposome 58 together with its change. Thus, external information can be transmitted through the optical stimulation from the first liposome to the second liposome via chemical substances.
