Outline of Final Research Achievements

In order to dramatically increase the controllability and development efficiency of molecular recognition materials for chemical sensor devices, smart materials were examined to have reconfigurable (initialization / re-setting capability), electrical control and tuning of molecular recognition properties to create moleculary electronic devices. The used materials were PVDF which is a piezoelectric material, and spiropyran and azobenzene which are photochromic materials which can control molecular recognition characteristics by voltage application and light irradiation on composite material with molecular recognizing structure (molecular imprinted polymer) in these smart materials. With the developed materials capablity of controlling the molecular recognizing properties, it is possible to realize a device capable of imparting a flexible molecular recognition function to numerous chemical substances and sensing chemical substances with extremely high efficiency.
