DOI: 10.1021/acs.orglett.0c03506
Abstract: Although many chiral molecules exhibiting circularly polarized luminescence (CPL) have been reported recently, few molecular design guidelines are known for increasing the dissymmetry factor for CPL (glum). We demonstrate that a figure-eight-shaped molecule with D2… read more here.

Diagnosing Ring Current(s) in Figure-Eight Skeletons: A 3D Through-Space Conjugation in the Two-Loops Crossing
Sign Up to like & getrecommendations! Published in 2022 at "Organic Letters"
DOI: 10.1021/acs.orglett.2c01625
Abstract: The macrocyclic structures with local conjugation readily undergo a redox-triggered change in the diatropic character, leading to a global current–density pathway of the doubly charged systems. The figure-eight geometry of the neutral dimer does not… read more here.

DOI: 10.1039/d2cc01696f
Abstract: Two oligoamide macrocycles composed of eight and twelve 7-amino-8-fluoro-2-quinolinecarboxylic acid monomers were synthesised despite the propensity of their acyclic precursors to fold and self-assemble into double helices. Macrocyclisations were made possible through the transient use… read more here.
