Natural melanin affects the reflection and absorption of light, and it is known as an important element in producing bright structural colors in nature. In this study, we prepared core-shell particles using a melanin precursor polymer, that is, po...
Inspired by the coloring mechanism of insects, we demonstrated the preparation of metallic luster materials by a combination of dye absorption and specular reflection from layered microcrystals. Metallic luster films were prepared by the recrystal...
Luminescent core–shell polymer particles carrying amino groups for covalent immobilization of enzymes were synthesized for practical applications in immunoassays. The polystyrene core particles were synthesized by miniemulsion polymerization of oi...
A chiral urea compound, N,N’-bis(4-(3,4,5-trialkoxyphenylmethyl)phenyl)urea (1a), possessing a long core and six chiral alkyl chains ((S)-citronellyl groups) was designed to construct a double helix supramolecular structure in a liquid crystal pha...
An inverse opal structure was created using artificial melanin particles composed of a polystyrene core and a polydopamine shell as the template. The melanin-mimicking polydopamine that remained inside the inverse opal structure effectively absorb...
<p>N,N'-bis(3,4,5-trialkyloxyphenyl)glutaramide and malonamide were synthesized and characterized. Both of the compounds exhibited a columnar liquid crystal phase in a wide temperature range including room temperature. In the second harmonic gener...
<p>Development of organic ferroelectrics in columnar liquid crystals (FCLCs) is desired for functional materials with flexibility and low environmental load. Though FCLCs have been achieved by adjusting the molecular shapes or the hydrogen bonds, ...
<p>In this study, we have aimed to achieve high-ordering and spontaneous chiral induction of columnar liquid crystal phases driven by the tight packing of peripheral bent tail-shaped chains. We synthesized a disk-shaped molecule surrounded by six ...
