Abstract
The present disclosure relates, according to some embodiments, to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may receive excited state energy from light-absorbing molecules. According to some embodiments, the present disclosure relates to molecules, including substituted propenoic amides (e.g., aryl substituted propenoic amides), that may quench, dissipate, and/or otherwise resolve excited state energy (e.g., as heat).
