Synthesis and Electronic Structure of A2B Type Halogen Atoms Substituted H3-Triarylcorroles

摘要

Seven electron-deficient A2B type H3-triarylcorroles have been synthesized and characterized.The solvent dependence of the electronic absorption and magnetic circular dichroism (MCD) spectra and a series of TD-DFT calculations have been used to analyze trends in the electronic structures.Significant differences are observed in the optical spectra when solvents of differing polarity are used,which can be assigned to the effect of NH-tautomerism.
