Sparsely substituted chlorins as core constructs in chlorophyll analogue chemistry. III. Spectral and structural properties

摘要

The availability of stable chlorins bearing few or no substituents has enabled a variety of fundamental studies. The studies described herein report absorption spectra of diverse chlorins, comparative NMR features of chlorins bearing 0–3 meso-aryl substituents, and X-ray structures of the fully unsubstituted chlorin and the oxochlorin.
