Abstract

We have synthesized and characterized various di-substituted liquid crystalline polyacetylene (di-LCPA) derivatives with chirality, lyotropic liquid crystallinity and photoluminescence. Through the formation of a chiral nematic liquid crystal (N^*-LC) phase, we were able to generate circularly polarized luminescence (CPL) on di-LCPA. The highly ordered N^*-LC phase of di-LCPA made it possible to exhibit CPL with a high emission dissymmetry factor. The lyotropic LC properties of di-LCPA can be advantageous in the manufacture of electroluminescence (EL) devices since the polymer emissive layer (PEL) of the EL device can be fabricated at room temperature.
