Course description and aims

1, The first half of this class will focus on two advanced topics of liquid crystals. They are ferroelectric liquid crystals including their sub-phases, and self-modulation structure formation observed at the phase transition between nematic and smectic c phases. Basic knowledge of the liquid crystal is required. Students should have the credit of Mat.P401 (Organic Optical Materials Physics). or have the equivalent knowledge. At the beginning of the class, a pre-examination will be done. .
2, For understanding of fundamental properties of organic functional materials, fundamental concepts of surface, interface, state of matter and optical properties are lectured.

Student learning outcomes

Acquiring specialized knowledge on advanced topics of liquid crystal sicience.
Understand important concepts necessary to design organic functional materials.


Chiral Smectic Liquid crystal, Phase transition, Selof-Organization, Solid/liquid interfaces, Polymer nanomaterials

Competencies that will be developed

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

Class flow

Screening examination will be done at the beginning of the first class. Students have to pass the examination to attend this class. This class will be done using interactive teaching.

At the beginning of each class, solutions to exercise problems assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to what is taught on that day to solve. Before coming to class, students should read the course schedule and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
