GreetingsGreetings
Takeko Matsumura, Director, MINERVA LIGHT LAB LLC

Minerva Light Lab started as a university venture based on research on "Rapid, high-efficiency synthesis of luminescent complexes using microwaves." Currently, our main activities include consulting on microwave chemical processes, custom production of low-cost, high-purity complex reagents using microwaves, and development of microwave equipment. The application fields of microwave chemistry in Japan are expanding year by year, and its application to future industries is expected. Microwave chemical technology, which features energy saving, environmentally friendly clean processes, and reduced work time, is a technology that will innovate future industrial structures. Literally, "every day is microwave," I hope to strive for the establishment and dissemination of microwave chemistry as a new science and technology.

- Name: Takeko Matsumura
- Affiliated Research Institution/Department/Position
- Minerva Light Lab LLC, Microwave Chemistry Department, Chief Researcher
- Research Topic
- Selective synthesis of luminescent substances by microwave thermal catalytic action and development of environmentally friendly reaction processes
- Research Content
- Green chemistry innovates conventional synthetic chemical processes and pursues environmentally friendly chemical processes. Microwave heating is a science and technology that plays a part in this. This research focuses on the catalytic action of microwave heating, regards it as microwave thermal catalytic action, targets luminescent substances that occupy an important position in the highly information-oriented society, develops rapid, high-yield synthesis methods by microwave thermal catalytic action, and conducts basic research on physical properties. At this time, reactions are conducted under effective microwave heating conditions such as high dielectric constant, high boiling point alcohol solvents, phase transfer catalysts, and solvent-free conditions, and microwave thermal catalytic action is examined. Also, luminescence characteristics and molecular alignment in various matrices (liquid crystal state, glass state, in polymers) are examined in detail, and the luminescence mechanism is elucidated at the molecular level. Based on these results, luminescent devices are prototyped and evaluated. Through this series of research, environmentally friendly chemical processes for luminescent substances are developed and applied.

- Research Topic
- Research on synthesis and magnetic properties of new chiral organic radical liquid crystals
- Research Content
- Successfully synthesized new chiral organic radicals containing chiral dinitroxyl radicals in the core. Research progressed focusing on clarifying the characteristics of linear molecules that chemically bond to the core. Since the synthesized molecules all show paramagnetic liquid crystallinity, first, liquid crystal properties were clarified optically, and further, magnetic susceptibility and ESR were measured to clarify their orientation characteristics, and the effects of magnetic fields on paramagnetic liquid crystals were examined in detail.

- Research Content
- Photodynamic therapy (PDT) and photodynamic diagnosis (PDD) are attracting attention as low-invasive cancer treatment and diagnostic methods with high QOL. This research hybridizes tumor-selective functional molecules (sugar, folic acid) and precious metals with natural product-derived life system pigments to develop ultra-selective advanced photomedical compounds for cancer cells, and aims to realize clinical development through a strong medical-engineering collaboration system with clinical medical scientists.
