Abstract
Conjugated organic molecules such as the 2-quinolinone family can be used as energy-donor molecules in photocatalysis because of their light absorbing and energy transmitting qualities. Good donor molecules have triplet excited states that are useful for photocatalysis due to their long lifetimes. The goal of this research was to build a near-infrared emission spectroscopy instrument to observe a triplet signal in a set of five previously synthesized 2-quinolinone molecules. A near-infrared absorbance instrument was built successfully with accurate measurements; however, there was no detection of the desired triplet emission signal.
