Melanin influences light reflection and absorption and is known to be one of the elements producing structural color, such as that in the feathers of birds. In this study, we used polydopamine (PDA), an artificial melanin, as a light-absorbing mat...

Spontaneous chiral induction in bent-core liquid crystal molecules is well-known in the field of liquid crystals, but the examples of rod-like molecules are extremely limited. In this study, as a new and simple approach to induce chirality from ac...
