AI Article Synopsis
- The study reports the creation of new compounds featuring a chromophore and a helicenic structure, focusing on their preparation and characterization.
- The enantiomers of various chiral molecules were successfully separated using chiral HPLC, with their racemisation rates also measured for unstable variants.
- Measurements of electronic circular dichroism (ECD) and circular polarized luminescence (CPL) were conducted, revealing significant responses in chiral porphyrins and Bodipys across a broad part of the visible spectrum.
Article Abstract
The synthesis of several new compounds containing a chromophore and a helicenic moiety is reported. The preparation, characterisation and some physico-chemical studies are detailed. In particular, the two enantiomers of several chiral molecules of this type were separated by chiral HPLC (both analytically and in a preparative way) and their racemisation rates were determined for short-lived species. Electronic circular dichroism (ECD) and circular polarised luminescence (CPL) measurements were performed for the compounds with a very long racemisation half-life. Chiral porphyrins and Bodipys both gave ECD and CPL responses over a large area of the visible spectrum.
