Synthesis and Spectroscopic Characterization of Dual Absorption BODIPY Type Dyes and their Light Harvesting Application in Polymer‐Based Bulk Hetrojunction Organic Photovoltaics

Abstract: We reported the synthesis and characterization of two new BODIPY type dyes with fluorine-bridged two chromophores, boron-dipyrromethene (BDP) and boron-diindomethene (BDI). Each of BODIPY dyes 7a and 7b has two strong absorption bands around 500 and 600 nm bearing high extinction coefficients (76,000 M -1 cm -1 for 7a and 71,000 M -1 cm -1 for 7b at 501 nm; 115,000 M -1 cm -1 for 7a and 110,000 M -1 cm -1 for 7b at 603 nm). For light harvesting enhancement of solar cell, we have fabricated bulk heterojunction … Show more

“…52 The excellent optical properties and easy synthetic modification of BODIPYs make them the most studied fluorophore, and they have been used as a potential candidate in dye-sensitized solar cells, sensors, photosensitizers, fluorescent switches, nonlinear optics, photodynamic therapy (PDT), laser dyes, light harvesting and bioimaging applications. 53–60 Normal BODIPYs exhibit an absorption in the green spectral region (about 500 nm), which is not appropriate for in vivo PDT. Alternatively, near-IR absorption is desired for in vivo PDT because light with such wavelengths enables deeper tissue penetration.…”
