| Research Abstract |
Controls of molecular self-assembly should allow to realize a variety of molecular properties. The purpose of our study is to control the molecular self-assembly on surfaces, and to clarify light emission properties from the self-assembled molecules induced by tunneling current of scanning tunneling microscopy(STM). In this study, we have investigated self-assembled properties of porphyrins, olgothiophenes, Alq3, and Ir(ppy) molecules on metal surfaces. In addition, the photon detection system for STM-induced light emission was developed, and the spectroscopic imaging system for investigating electronic properties of the self-assembled molecules was also developed.
