Synthetic Manipulations of Pyrroles, BODIPYs and aza-BODIPYs

B9200 @ 3:30 p.m.

Host: Dr. Roger Linington

Abstract

Complexes of dipyrrins (dipyrromethenes) are extensive, with the most common involving boron. Dipyrrinato complexes of the –BF2 unit are termed BODIPYs. Aza-dipyrrins bear a nitrogen atom at the meso position, and their –BF2 complexes are known as aza-BODIPYs. These compounds exhibit desirable photochemical properties, and have broad use across chemical biology and materials science.

This talk will focus on efficient synthesis of BODIPYs and aza-BODIPYs, with the goal being to provide practical and efficient routes to complexes with tunable and robust physical and electronic properties. The synthesis of –BClcomplexes will be discussed, as will nucleophilic substitution and deprotection at boron.
