This seminar overviews the recent research achievements of Dr. D. Miyajima, a unit leader in RIKEN. His research goal is to develop emergent materials and contribute to our society. As a supramolecular chemist, he has tackled this challenge by elaborately designing intermolecular interactions between molecules. Among his seminal research achievements, the following (1)–(4) will be briefly introduced and the details of (5) and (6) will be mainly discussed.
- Chain-growth type supramolecular polymerization (Science 20151, Nat. Chem. 20172).
- An ultra-fast responsive jumping film actuator (Nat. Mater. 20163)
- Self-replicating synthesis of phthalocyanines (Nat. Mater. 20224)
- MRI contrast agents with iron-oxide nanoparticles (US Patent5)
- Delayed fluorescence from inverted singlet and triplet excited states (Nature 20226)
- Novel bulk photovoltaic effect in organic polar assemblies (JACS 20207, Angew. Chem. Int. Ed. 20218)
Although these topics are irrelevant to each other at a glance, their key concepts were based on deep insights from the viewpoint of intermolecular interactions. In this seminar, Dr. Miyajima will outline the particular topics and introduce how he came up with the ideas that led to the achievements.

Dr. Miyajima is a chemist interested in the self-assembly of molecules and their emergent functions. He earned his Ph.D. from the University of Tokyo in 2013. He worked as a sub-group leader with prof. Takuzo Aida in RIKEN for five years, then became a Unit Leader (PI) in RIKEN CEMS in 2018. He also has worked as a deputy team leader of the hydrogen energy storage technology laboratory team since 2018. In 2021, he was selected as a Principal Investigator for the PRESTO project (Sakigake) supported by Japan Science and Technology Agency (JST).
