  Synthesis of a new type of dibenzopyrromethene–boron complex with near-infrared absorption property

  摘要：

  A new type of pi-extended 4-bora-3a,4a-diaza-s-indacene (BODIPY dye), bis(isoindole)-derived benzo-[1,3,2]oxazaborinine 1, has been synthesized by seven-step procedure from 2-methoxybenzoic acid methyl ester. The benzannulation of the pyrrole ring and the formation of a structurally Strained intramolecular B-O ring enable the dye to absorb near-infrared light at ca. 750 nm with a molecular extinction coefficient (epsilon) of ca 8.3 x 10(4) M (1) cm (1) in THE The absorption properties are discussed on the basis of DFT Calculations. Interestingly, a film of 5,5-dihexyloxy derivative 1b, which was fabricated by a spin-coating procedure on a glass plate, exhibited a dramatic bathochromic shift of absorbance as compared to the solution, with lambda(max) of 922 nm.
