Material and Life Science -> Molecular System Engineering (Research)
MENU : Research Lab. news

     The 21st century is said frequently to be the age of photonic information network. The extensive expectation is grawing up in developing new opto-electronic materials and new devices to make the dream possible. In our lab, we are forcusing on organic materials as a promising material, which may open new avenue, for developing such new functional devices with well-defined molecular alignments.
     Our research stance is based on the viewpoint that we, chemists who provide materials, should develop not only devices but also system in advance by ourself taking the best use of new properties and new reaction discovered by ourself. When we do background science from this point of view, we can experience true joy of doing Science and can enjoy the dream of future. This is our motto.
     Let's makes your dreams held in your young time come true with us!

Our recent projects going on in this lab are as follows:
