In this tutorial, we guide the reader through two alternative approaches to calculation of circular dichroism (CD) spectra chiral supramolecular assemblies non-chiral chromophores. The seemingly different rely on same basic approximations and are therefore expected lead similar results. For a dimer, obtain explicit analytic expressions for CD responses in demonstrate perfect equivalence methods. Numerical results larger systems further validate result. We hope that tutorial will help young...
Herein, we report the synthesis and chiroptical characteristics of first (double) helicenes possesing 1,4‐dihydropyrrolo[3,2‐b]pyrrole (DHPP) moiety as their central core. We have developed a three‐step with 6π‐electrocyclization accompanied HBr elimination its key step. found that, whereas for smaller periphereal arms double occurs smoothly forming helicene, in case longer policyclic aromatic hydrocarbons reaction becomes less efficient mono‐helicenes are only products.

Some achiral cyanine dyes form well-ordered chiral assemblies exhibiting pronounced Circular Dichroism (CD) and Circularly Polarized Luminescence (CPL). Notably, C8O3 cyanines self-assemble into tubular J-aggregates, which further organize bundles displaying bisignate CD spectrum - hallmark of an exciton coupled system unusual bisignated CPL. In contrast, the aggregates display a monosignate spectrum. The mechanism underlying these intriguing features remains elusive. present work,...
