Research Content & Progress:
To study quantum manipulation/control in molecular and spintronic systems, some new instruments have been designed and set up recently. For example, the multiple reflection-transmission infrared spec-troscopy has much higher signal to noise ratio. With the programmable DNA self-assembling technique, we realize the precise control of nano-devices, especially nano-robots. Through the introduction of bar-coding organic molecule onto the nanostructure surface, a diagnostic scheme for the detection of DNA interaction and hybridization process has been developed.
Importantly, we have successfully designed and built a combined molecular beam epitaxy (MBE) and low temperature scanning tunneling microscopy (LT-STM) system. With this system, one can prepare various magnetic nanostructures and in-situ study their structure and magnetic properties. In addition, the magnetic transport behavior can also be studied with a newly built variable temperature magneto-transport system.
From delocalized molecule-orbital and exciton theories, the charging and energy transferring in excited states and quantum manipulation for photo excited state in molecular system are studied. A highly con-jugated core-modified Rubyrin with meso-aryl substituents and phenanthrene-fused pyrrole rngs is suc-cessfully prepared and it shows intense absorption in near-infrared region, which is useful as molecular switches and sensors. A novel meso-aryl-substituted [14]Triphyrin is synthesized by a facile approach.
The ferroelectric thin films based on mononuclear lanthanide enantiomers are fabricated and they dis-play ferroelectric and dielectric properties at room temperature.
