Helical systems, known for their high optical rotations and strong cotton effects, have not been explored for chirality sensing applications based on Cotton effects in circular dichroism spectra. The authors propose developing rationally-designed helical platforms for chirality sensing and assay. They propose that these systems undergo rapid enantiomerization at room temperature, resulting in racemic systems that exhibit no CD signals. However, when a chiral analyte is bound to a racemic helical probe, it induces a CD signal with a particular Cotton effect, which in turn contributes to the Cotton effect. The authors propose developing rationally-designed helical platforms for chirality sensing and assay. They also propose that electro-generated light can pass through organic layered filters with less attenuation due to circular polarization, leading to increased image brightness with lower power consumption. Helicenes are considered inextricable platforms for designing CP-OLED materials. The authors consider the following factors for better CPL activity: large molecular structures, helicenes' larger size, the introduction of heteroatoms and donor-acceptor attributes, and rigid and contrived high molecular-weight structures. They propose synthesizing C2- and C3-symmetric helicenes and demonstrating their utility as CP-OLEDs. These investigations are topical and not practiced in the country, adding a new dimension to the field.
