| Outline of Final Research Achievements |
An organic field-effect transistor was fabricated using diarylethene and photoswitching of semiconductor characteristics was demonstrated. Drawing of a transistor circuit was demonstrated by irradiating ultrafine light to the thin film of photoresponsive transistor made of a diarylethene and converting an irradiated part from insulator to semiconductor. In a photoresponsive transistor made of a diarylethene having benzothienothiophene ring as a side chain, the closed-ring isomer generated by irradiation with ultraviolet light has been found to exhibit an ambipolar characteristic that shows not only p-type but also n-type operation.
