Popis:	Small molecules having fluorescence quantum yields are required to promote biological and organic material applications. In this work, we introduced a series of pyridinyl coumarincarboxymides derivatives, namely 4-XP. These compounds exhibited intense blue fluorescence with high fluorescence quantum yield. By spectral measurement and analysis, it is identified that these pyridine-coumarin conjugates displayed high fluorescence quantum yields (ΦF = 0.77–0.82) blue fluorescence at about 455 nm in nonpolar solvents. Additionally, the solvent effect and fluorescence properties were verified and explained by DFT and TD-DFT calculations.
