| dc.description.abstract | Nine chromophores with ferrocene donor and pyridine/pyridinium acceptors have been prepared and further investigated. The performed X-ray analysis showed partially polarized and geometrically oblate pyridine unit. An extension of the pi-system and N-quaternization were revealed as suitable tools for exclusive manipulation of the LUMO with the almost steady HOMO. Whereas the electrochemical HOMO-LUMO gap can be tuned from 3.01 to 1.49 eV, the high- and low-energy absorption bands were found within the range of 280-402/456-547 nm. The pyridinium chromophores showed distinct negative solvatochromism. A thorough DFT analysis has been performed; it turned out that ferrocene donor is capable of two principal D-A interactions, whose employment depends on the appended electron-withdrawing moiety. | eng |

Provedené X-ray analýzy potvrzují částečně polarizovanou a planární pyridinovou jednotku. Rozšíření pi-konjugovaného systému a N-kvarternizace vedou k posunu LUMO s téměř ustáleným HOMO. Elektrochemický rozdíl HOMO-LUMO se mění v rozmezí od 3.01 do 1.49 eV a vysoko- a nízkoenergetické absorpční pásy byly pozorovány v rozmezí 280-402 resp. 456-547 nm. | cze |
