cze	Studium vztahů mezi strukturou a reaktivitou na skeletu N.N-dimethylamino-fenylen-acetylen	Cross-couplingovými reakcemi (Suzuki-Miyaura a Sonogashira) bylo připraveno sedm donorně substituovaných fenylenethylenů s až třemi 1,4-fenylenovými jednotkami a až dvěma acetylenovými jednotkami. Byla měřena jejich absorpční a emisní spektra a byly provedeny teoretické výpočty. Za účelem studia mezi strukturou a reaktivitou byl systematicky prodlužován skelet molekul spojující NN-dimethylamino skupinu a terminální acetylenovou jednotku.	acetylen, fenylen, pi systém, absorpce, emise, donor
eng	N,N-dimethylamino-phenylene-acetylene scaffolding: Structure-property relationships	Seven model donor-substituted phenyleneethynylene molecules with up to three 1,4-phenylene and two acetylenic units were synthesized by Suzuki-Miyaura and Sonogashira cross-coupling reactions and further studied by absorption and emission spectra and theoretical calculations. The pi-system between the N,N-dimethylamino group and terminal acetylene was systematically elongated which allowed elucidation of the fundamental structure-property relationships. Structural factors such as molecular length and chromophore planarity proved to be crucial for the observed spectroscopic behavior.	Acetylene; Phenylene; pi-System; Absorption; Emission; Donor
