Aza-BODIPYs are sub-class of BODIPYs and very promising candidates as NIR dyes due to their strong absorption and emission properties around 600-800 nm range and versatile structures.1 The BODIPYs and aza-BODIPYs have found applications in optoelectronics, bio-imaging, sensing, and PDT.2-4 The optical properties of aza-BODIPYs can be tuned by substituting aza-dipyrrin core at 3,5- or 1,7-positions by other moieties. Tetraphenylethyene (TPE) and Hexaphenylsilole (HPS) show aggregation induced emission (AIE). Due to their AIE property can be used to prepare new fluorescent probes.
Our group at IIT Gandhinagar is involved in the chemistry of BODIPY and aza-BODIPY derivatives,2-4 dipyrrins complexes5 and porphyrins.6 In this poster, synthesis, electrochemical, optical, and energy transfer studies of the aza-BODIPYs derivatives will be discussed.
