Aggregrates of substituted {6}helicene compounds that show enhanced optical rotatory power and nonlinear optical response and uses thereof

摘要

This invention provides a compound having the structure: wherein rings A and B represent independent electron accepting ring systems and wherein R1, R2, R3, R4, R5, R6, R7 and R8 are the same or different and are H, substituted or unsubstituted, saturated or unsaturated alkyl, alkenyl, cycloalkyl, aryl, or arylalkyl, -SR, -NRR', -OR, -OC(O)R, SC(O)R, -SCR, wherein R and R' are independently substituted or unsubstituted, saturated or unsaturated alkyl, alkenyl, cycloalkyl, aryl, or arylalkyl. This invention also provides thin films comprising a compound having the above structure or suitable derivatives thereof. This invention further provides liquid crystal display devices and non-linear optical devises comprising a compound having the above structure or a suitable derivative thereof. Finally, this invention provides a method for achieving a high order non-linear electrooptical response comprising contacting a suitable sample of the inventive compound or a derivative thereof with an appropriate light source.
