Towards Understanding the Solvatochromatic Behavior of Fluorenone and Benzofluorenone Derivatives in Protic Solvents

, 2022
In this paper, we investigate the solvatochromatic behaviors of fluorenone and benzofluorenone derivatives in both protic and aprotic solvents. While the effects of aprotic solvents on these dyes have been extensively studied in silico, little has been ...
