Two new star‐shaped molecules 1 and 2 containing a triphenylamine/benzene moiety as the central core and three 2,4‐dicyano‐3‐diethylamino‐9,9‐diethylfluorene moieties as the peripheral functional groups were synthesized and characterized. Charge transfer properties for these compounds were observed in photophysical experiments due to their D‐A molecular structure. Compound 1 presented dual fluorescence in high polar solvents. Moreover, these compounds exhibited moderate fluorescence and high thermal stabilities, indicating their potential application to blue light emitting materials.
