Preparation of Stimulus-Responsible Materials for Single Molecular Devices and their Functionalization
Research Aim
In our previous studies, we achieved high purity synthesis of highly conjugated compounds, a basic evaluation of their physical properties, the development of coated conversion-type organic field-effect transistors and organic solar cells, and the synthesis of near-infrared specific absorbing dyes. In the present study, we aim to create single molecular devices that respond to external stimuli using high purity highly conjugated π-electron system compounds.
Role and Need in the Group
It is important when creating single-molecular devices that optimal compounds are prepared with high purity. Organic synthesis is our area of strength, and by using a high purity synthesis of highly conjugated π-electron compounds by a precursor method, we can provide the necessary compounds with reliable purity to research groups in the area, regardless of the plan or proposal.
Research Content
Our group will focus on the following two activities:
1. Effects of integration patterns: Use an external stimulus to transform highly conjugated compound precursors on the substrate, distinguish the integrated morphology, and measure and evaluate the electrical properties.
2. Creation of external-stimulus-response-type single molecular devices: Measure and evaluate single-molecule devices equipped with a molecular wire on the highly conjugated compound precursor and the electrical characteristics of monomolecular elements after applying external stimuli.
