Steady-state spectroscopy and ultrafast dynamics of flavylium derivatives in the red and near-infrared spectral region

In an effort to enhance the absorption and fluorescence of flavylium in the red and near-infrared (NIR) spectral region, we synthesized a 2′-hydroxyflavylium derivative (FLV-OH) with a rigid electron donating julolidine group attached to position 7 and examined its ground and excited states spectros...

Description
Summary:In an effort to enhance the absorption and fluorescence of flavylium in the red and near-infrared (NIR) spectral region, we synthesized a 2′-hydroxyflavylium derivative (FLV-OH) with a rigid electron donating julolidine group attached to position 7 and examined its ground and excited states spectroscopy by absorption, fluorescence, ultrafast dynamics, and by density functional theory (DFT). The current results indicate that FLV-OH has spectroscopic properties that make it suitable for many applications such as a potential light harvesting dye in solar cell.
