Kulhanek, Jiri published the artcileQuadrupolar fluorophores with tetrafluorobenzene central electron acceptor, COA of Formula: C11H17BO3S, the publication is Journal of Fluorine Chemistry (2021), 109735, database is CAplus.
Seven novel quadrupolar chromophores based on 1,2,4,5-tetrafluorobenzene (TFB) central electron acceptor unit and methoxythiophene peripheral donor were synthesized and described. Fundamental structure-property relationships were elucidated via thermal, electrochem. and optical measurements. These revealed that the properties are mostly affected by the used π-linker. Variation of the π-linker resulted in tuning of the HOMO-LUMO gap. The LUMO clearly reflects planarity, polarizability and electronic transparency of the utilized π-linker. The absorption maxima of target chromophores were found within the range of 346-412 nm and the emission maxima of emissive derivatives were found within the range of 411-499 nm. Novel TFBs were compared with TFBs previously described in the literature. The exptl. data are further corroborated by theor. calculations
