Synthesis of novel benzobacteriopurpurins by Diels-Alder cycloaddition
A new class of stable bacteriochlorins, namely benzobacteriopurpurin bearing two exo-cyclic rings was synthesized by way of Diets-Alder cycloaddition of 8-vinyl-mesopurpurin-18 methyl ester with tetracyanoethylene (TCNE) and dimethyl acetylenedicarboxylate (DMAD). These novel bacteriochlorins have long wavelength absorptions in the range of 760 to 795 nm.
