eng	Synthesis and Properties of Tetrafluorobenzene Push-Pull-Push Chromophores with Thiophene Moiety	The organic, readily polarizable push-pull-push systems are currently tremendously investigated due to their nonlinear optical properties and thus resulting application in modern optoelectronic devices. We report herein synthesis and properties of seven novel systems featuring 5-methoxythienyl 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, 1,4-phenylene and 2,5-thienylene subunits. Synthesized compounds were fully characterized by NMR and MS as well as by absorption and emission spectroscopy. Their comparison with 1,4-phenylene analogues and influence of the p-linkage will be discussed.	Tetrafluorobenzene; Push-Pull-Push chromophores; Thiophene
