eng 3,4-Dinitrothiophene-derived chromophores: Synthesis and properties 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 nine novel systems featuring 5-methoxythienyl donor and 3,4-dinitrothiophene acceptor moieties. The π-linkage has been formed by systematic extension of the π-conjugated path by ethenylene, ethynylene, 1,4-phenylene and 2,5-thienylene subunits. Synthesized compounds were fully characterized by NMR and MALDI-MS as well as by absorption and emission spectroscopy. Their comparison with 1,4-phenylene analogues and influence of the π-linkage will be discussed. NLO properties, optoelectronics, 3,4-dinitrothiophene, cross-coupling
