Synthesis and photophysical properties of push-pull structures incorporating diazines as attracting part with a fluorene core

We report, herein, the synthesis of new push-pull chromophores that incorporate a diazine ring as the electron-withdrawing part and an N,N-dimethylaniline moiety as the electron-donating part. Both of which are connected to a fluorene core. The length of the conjugated backbone was increased by incorporating ethynyl linkers and triazole rings on the both sides of the fluorene. The optical and two-photon absorption (TPA) properties were investigated, which exhibitied high quantum yields (up to 70 %), significant Stokes shifts, and good TPA cross-sections. New push-pull fluorophores have been synthesized that contain a diazine ring as the electron-withdrawing part and an N,N-dimethylaniline moiety as the electron-donating part. Both of which are connected to a fluorene core. The syntheses of these structures consist of a copper-catalyzed Huisgen 1,3-dipolar cycloaddition as well as Sonogashira and Suzuki cross-coupling reactions. Copyright
