cze	Push-pull molekuly na bázi 4,5-dikyanimidazolu se systematicky rozšiřovaným π-konjugovaným systémem	Celkem 18 chromoforů na bázi 4,5-dikyanimidazolu se systematicky prodlužovanou π-konjugovanou cestou a methoxy a N,N-dimethylamino skupinami jako donory byly připraveny a charakterizovány pomocí X-ray analýzy, elektrochemie, UV-Vis spektroskopie, fluorescence. NLO vlastnosti byly rovněž kalkulovány. Dále byly vyhodnoceny vztahy struktura-vlastnosti.	push-pull chromofory; imidazol; donor-akceptorní systém; elektrochemie; UV-Vis spektroscopie; NLO
eng	Push-pull molecules with a systematically extended π-conjugated system featuring 4,5-dicyanoimidazole	Eighteen chromophores featuring 4,5-dicyanoimidazole as an acceptor moiety, a systematically enlarged π-conjugated spacer and methoxy and N,N-dimethylamino groups as donors were synthesised and characterised by X-ray analysis, electrochemistry, UVeVis and fluorescence spectroscopy whilst NLO properties were calculated. Quantitative relationships between measured properties and structural features of the chromophores were also evaluated.	push-pull chromophores; imidazole; donor-acceptor system; electrochemistry; UV-Vis spectroscopy; NLO
