Course description and aims

This course is for students in Tokyo Tech-Tsinghua University joint graduate program. The course is held at Tsinghua University in Beijing and mainly deals with the fundamental concepts of soft materials. Since the instructors and the topics change every year, the course contents will be revised every year. This year, the course will be divided into two: the former half will deal with structure and physical properties of soft matters including liquid crystal and polymers and the latter half will be synthesis and applications of organic semiconducting polymers.

Student learning outcomes

At the end of the course, students will acquire the following abilities:
1) Students will gain an understanding of thermodynamics of the hierarchical structures and the physical properties of soft matters and several analytical methods for them.
2) Students will understand how to produce organic semiconducting polymers and structure-property relationship.


Liquid crystal, block copolymer, polyimide, self-organization, X-ray scattering, vibrational spectroscopy, polarized light, Organic semiconductor, Polymer synthesis, Cross-coupling reaction, Organic electroluminescence, Organic transistor, Organic photovoltaics

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

This course will proceed in the following order: (1) hierachical structures of soft matters including polymers, (2) organic semiconducting polymers.
