eng	New Chromophore and Fluorophore Based on Tetrafluorobenzene	The organic, readily polarizable push-pull-push systems are currently tremendously investigated due to their nonlinear optical properties and/or fluorophore properties and thus resulting application in modern optoelectronic devices. We report herein synthesis and properties of sixteen novel systems featuring dimethylamino and methoxy group as donor and 2,3,5,6-tetrafluorobenzene acceptor moieties. The p-linkage has been formed by systematic extension if the p-conjugated path by ethenylene, ethynylene and 1,4-phenylene subunits (Figure 1). Synthesized compounds were fully characterized by NMR and MS. The absorption and emission spectroscopy has been performed. The NLO characteristic have been computed and compared with experimental date.	Chromophore; fluorophore; tetrafluorobenzene
