Description

The chiral nematic prepared by mixing enantiomeric ruthenium complexes with 5CB was observed at room temperature. The sample was put on a glass slide without cover glass under crossed polarizers. The texture that looks like the assembly of clock-hands was taken in collaboration with Mr. Shuhei Tamura. The width of the figure is about 700 microns. The details are available in Chem. Commun., 2017, 53, 5103-5106.

Jury comment

It looks like bushes of hemp, but this is a very curious clock-like domains appearing in a cholesteric mixture of 5CB and a metal complex.
