cze Quadrupolaární fluorofory s tetrafluorbenzenem jako centrálním elektronakceptorem Bylo syntetizováno a charakterizováno sedm nových kvadrupolárních chromoforů na bázi 1,2,4,5-tetrafluobenzenu jako centrálního elektronakceptoru a methoxythiofenovými postranními donory. Vztahy struktura-vlastnosti byly studovány termickými, elektrochemickými and optickými metodikami. Absorpční maxima chromoforů byla pozorována v oblasti 346-412 nm a emisní maxima emitujícíchc derivátů v oblasti 411-499 nm. Experimentální data byla konfrontována s teoretickými kalkulacemi.

eng Quadrupolar fluorophores with tetrafluorobenzene central electron acceptor Seven novel quadrupolar chromophores based on 1,2,4,5-tetrafluorobenzene (TFB) central electron acceptor unit and methoxythiophene peripheral donor were synthetized and described. Fundamental structure-property relationships were elucidated via thermal, electrochemical and optical measurements. These revealed that the properties are mostly affected by the used p-linker. Variation of the p-linker resulted in tuning of the HOMO-LUMO gap. The LUMO clearly reflects planarity, polarizability and electronic transparency of the utilized p-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 experimental data are further corroborated by theoretical calculations.
