제목 Fabrication of Various Sensor Systems Using Polydiacetylenes
초록 Polydiacetylenes (PDAs) have a special character in which their color changes from blue to red by outer stimuli. 1) A glucose sensor was fabricated using a PDA. H2O2 formed by the reaction between glucose and glucose oxidase functioned as the initiator. The glucose concentration could be detected that turns the solution to blue. 2) PDA and poly(sodium 4-styrene-sulfonate) (PSS) were alternately stacked to form a layer-by-layer (LBL) film. The formed-film sensor showed higher sensitivity than the vesicle solution. 3) The noble vesicular system of PDA showed a red shift by the permeation through the vesicular layers from within the vesicle. 4) The thermal chromatic sensitivity of PDAs with 10,12-pentacosadiynoic acid (PCDA) derivatives which have a hydroxyl group (HEEPCDA) were investigated. The vesicle solution with polymerized HEEPCDA exhibited a reversible chromatic response during the heating and cooling cycle in D2O, but not in H2O.
