Synthesis of π-expanded O-chelated boron–dipyrromethene as an NIR dye
摘要:
A pi-expanded BODIPY dye with an intramolecular boronate skeleton was synthesized by retro Diets-Alder reaction of the bicyclo[2.2.2]octadiene (BCOD)-fused BODIPY and the subsequent O-chelation. The photophysical and electrochemical properties were examined by UV-vis, fluorescence, CV measurements, and DFT calculation. This BODIPY exhibited the absorption and emission over a visible-NIR region at 600-850 nm. O-chelated BODIPY showed a bathocromic shift compared to F-BODIPYs. This dye showed a bright fluorescence emission at 733 nm with the high phi value of 0.58. (C) 2011 Elsevier Ltd. All rights reserved.

π-Conjugated aza-BODIPYs with absorption in the near-infrared region have attracted attention, but there are few reports of their synthesis. We report the synthesis and absorption properties of π-conjugated asymmetricaza-BODIPYs by nitrosation and retro-Diels-Alder reaction of bicyclo[2.2.2]octadiene-fused bicyclopyrroles. We also synthesized aza-BODIPY fused with [2.3]naphtho and [2.3]anthra structures
