The biggest challenge facing my generation of scientists is to develop chemistry for a sustainable society.
The most important future application of my research is artificial photosynthesis.
I chose chemistry as a career because it is a field full of surprises and discoveries and has the feasibility for significant contribution for society.
The most important factors in the choice of my current research topic were passion and opportunities.
Key experiences in my education / career were the extensive discussions with my respected mentors.
The next big goal of my research is the biological application of circularly polarized luminescence.
In five years, I hope to be a good chemist and mentor.
I recharge my batteries by eating chocolate.
If I were not a scientist, I would be an engineer.
My biggest motivation is to make someone happy.
Guaranteed to make me laugh are interesting animal videos.
If I could be described as an animal it would be as a dog.
My motto is to do my best, anytime.
The natural talent I would like to be gifted with is the communication ability to make a good relationship with any person in the world.
My favorite way to spend a holiday is having a slow day with my family.
Behind the Science
This work describes an approach to molecules exhibiting bright circularly polarized luminescence (CPL). The cyclodextrin derivatives with multiple pyrene units were designed and synthesized by the members in our laboratory. We were very happy and surprised, when the good CPL properties and the odd–even effect of the pyrene-cyclodextrin derivatives were revealed. The biggest obstacle of this study was the structural study of pyrene-cyclodextrins. The compounds can form various conformations due to six flexible pyrene units. The obstacle was overcome by cooperation of Prof. Mori and Prof. Nagata who are experts in theoretical calculation, and the plausible conformer showing bright CPL could be determined.
