Abstract
The invention provides a liquid crystal cell and method thereof. The cell comprises two opposed substrates and a surfactant-free lyotropic chromonic liquid crystals (LCLC) material disposed therebetween. By using an ammonium compound with LCLC or surface treatment on the substrates, the alignment of the LCLC material can be manipulated as a homeotropic bulk alignment; or a hybrid bulk alignment in which the LCLC alignment is changed from homeotropic bulk alignment in the vicinity of one substrate to planar alignment in the vicinity of another substrate. The cell can be used in biosensing, detection and amplification of ligands, optical devices, and photovoltaics etc.
