Doubly N-confused phlorin and phlorinone analogue†
Abstract
A doubly N-confused phlorin and phlorinone analogue were synthesized from a β,β′-linked dipyrromethane precursor and characterized by means of NMR and UV-Vis spectroscopies, X-ray crystallography, and electrochemistry. Solvents have a considerable impact on the optical absorption of the doubly N-confused phlorin so that it can differentiate simple alcohols such as methanol and ethanol.
