Summary: | PROBLEM TO BE SOLVED: To form a sensitive film, by introducing an objective dopant into a pure conductive polymer even if the conductive polymer is insoluble to a solvent. SOLUTION: 3-n-octylpytrrole and 12 tungsto(VI) phosphoric acid with equal mol equivalent as that of 3-n-octylpyrrole and FeCl3 with mol equivalent 1/2 that of 3-n-octylpyrrole are dissolved in acetonitrile and, by oxidative polymn. method, poly(3-n-octylpyrrole) containing FeCl3 is polymerized. This poly(3-n- octylpyrrole) is subjected to Soxhlet extraction using methanol as a solvent to remove FeCl3 . 12 tungsto(VI) phosphoric acid remains in poly(3-n-octylpyrrole). This poly(3-n-octylpyrrole) is dissolved in chloroform and the soln. is applied to a glass substrate 1 by spin coating to form a sensitive film 7. |
