Abstract
Mesomorphic substances were discovered in the latter part of the last century and Reinitzer is generally accredited with the early work on cholesteric liquid crystals (34). The cholesteric mesophase is unique in that it can scatter white light to form brilliant colors. Nearly all cholesteric substances are esters of cholesterol. These compounds have a negative optical activity with an unusually large rotation. This large rotatory power is due to the unusual arrangement of molecules and not to the asymmetry of the individual steroid molecules. The colors formed by the cholesteric mesophase are due to the scattering of white light (circular dichroism). While one circularly, polarized component of the incident beam is reflected, the other is scattered, resulting in the formation of the classical iridescent colors generally associate with this mesophase (13).
This work represents part of the research partially fulfilling the requirements for the Degree of Doctor of Philosophy at St. Louis University.
