Welcome to the Toyota laboratory!

 "Physical Organic Chemistry" is chemical research area in which we study structure, properties, and reactivity of organic compounds precisely in order to disclose new principles and theories for the relationships between molecular structures and their properties. Based on the idea, we design and synthesize novel organic compounds with unique structure, and we investigate their structure and chemical properties by spectroscopic measurements and theoretical approach.
 Recently, we focus on development of novel "simple yet elegant" π electronic units and we apply them to construct functional 2D or 3D organic architectures. Our research policy is "Design new molecule outside the box, Make the molecule, and Study to find charmy aspects of the molecule".

 We are now recruiting undergraduates, graduated students, and post-Docs. Feel free to contact us if you intend to take a look into our laboratory. Link to address page
