The article explores the intricate relationship between chiroptical properties and molecular symmetry of pyrene-conjugated single and double [7]helicene.
Enantiopure [7]helicenes were utilized as molecular wrenches at the terminal K-regions of the conjugated pyrene nanoribbon to achieve a 99.9% conformational population of a single-handed helical ribbon with an end-to-end twist of 171°.
Chiral nanographenes: molecular architecture, key constituents, and their circularly polarized luminescence.
This feature article summarizes the recent developments of azahelicenes showing circularly polarized luminescence.
This review will highlight several recent and lesser-reviewed works related to the preparation of chiral nanographenes, specifically focusing on structures prepared by non-Scholl methods.
