    • نبذة مختصرة :
      A series of tripodal push-pull chromophores based on central indan-1,3-dione scaffold has been designed and synthesized by Knoevenagel condensation and Pd-catalyzed Suzuki-Miyaura cross-coupling reaction. Target molecules possess D -pi - A (pi-A)(2) extraordinary T-shaped structural arrangement. The electron donor attached at C2 position as well as the peripheral acceptor branches at C4 and C7 positions of the parent indan-1,3-dione have been systematically modified to achieve property tuning. Fundamental thermal and optoelectronic properties have been investigated by differential scanning calorimetry, electrochemistry, UV/Vis absorption spectroscopy, and DFT calculations. Based on the experimental and theoretical data, we herewith discuss thorough structure-property relationships.
      Byla připravena série trojramenných push-pull chromoforů s centrální jednotkou indan-1,3-dionu, syntézy byly provedeny prostřednictvím Knoevenagelovy kondenzace a Pd-katalyzované Suzuki-Miyaura cross-couplingové reakce. Cílové molekuly mají tvar písmene T. Za účelem ladění vlastností molekul byly na centrální jednotce indan-1,3-dionu systematicky substituovány poloha C2 pomocí elektrondonorních substituentů a polohy C4 a C7 pomocí elektronakceptorů. Termální a optoelektronické vlastnosti byly studovány pomocí DSC, elektrochemicky, UV/Vis sbsorpční spektroskopií a DFT kalkulacemi. Jsou diskutovány vztahy struktura-reaktivita.
