ABSTRACT:
A method for producing a blend comprising randomly substituted mesogens comprising: providing one or more platform molecules have the following general structure:wherein at least one member selected from the group consisting of X and Y comprises one or more spacer groups; R2is a bulky organic group whereby, when both X and Y are reacted with polymerizable groups to produce polymerizable mesogens, R2provides sufficient steric hindrance to achieve a nematic state at room temperature while suppressing crystallinity of the polymerizable mesogens at room temperature; and, R1and R3are selected from groups less bulky than R2; and independently substituting at least one member selected from the group consisting of X and Y with a polymerizable group, thereby producing a blend of randomly substituted mesogens.
