First report of trans-A₂B-corrole derived from a lapachone derivative: photophysical, TD-DFT and photobiological assays.

ABSTRACT: In this work, the synthesis, characterization and photophysical assays of a new trans-A₂B-corrole derivative from the naturally occurring quinone are described. β-Lapachone is a naturally occurring quinoidal compound that provides highly fluorescent heterocyclic compounds such as lapimidazoles. The new trans-A₂B-corrole compound was obtained from the reaction between 2,3,4,5,6-(pentafluorophenyl)dipyrromethane and the lapimidazole bearing an aldehyde group. The dyad was characterized by high-resolution mass spectrometry (HRMS), NMR spectroscopy (¹H, COSY 2D, HMBC, ¹⁹F), FT-IR, UV-vis, steady-state and time-resolved fluorescence, electrochemical studies (CV), TD-DFT analysis and photobiological experiments, in which includes aggregat
