Molecular chirality realizes strongly in the condensed phases(crystals, membranes, gels), however, it cannot be generally measured by commercially-available spectrophotometers due to strong macroscopic anisotropies. We have developed novel Universal Chiroptical Spectrophotometers, UCS-1~3, which overcome these problems. UCS-1 provides all optical characteristics. UCS-2/3 measure transmittance and Diffuse Reflectance CD, with vertical incident light and a horizontal sample stage, ideal for a droplet of solutions, loose powders or gel, to reveal structures and the dynamics of the transition processes. In this article, I shall describe the difficulty of solid-state chirality measurements, principles/outlines of UCSs and several examples of rich information obtained using UCSs.
