Multipodal arrangement of push-pull chromophores: a fundamental parameter affecting their electronic and optical properties

Popis výsledku v původním jazyce

A series of model push-pull molecules with linear, quadrupolar, and tripodal arrangements, a varyingly substituted amino donor, two acceptors, and a partially extended pi-system has been prepared. Two peripheral electron acceptors, namely N, N&apos;-dibutylbarbituric acid and dicyanovinyl, were employed. The fundamental properties of 24 push-pull chromophores were investigated by differential scanning calorimetry, electrochemistry, one-photon absorption spectroscopy, photoinduced piezooptics, and were supported by DFT calculations. Thorough structure-property relationships were elucidated, while a significant influence of the structural arrangement/branching on the electronic and optical properties has been revealed. The fundamental optoelectronic properties of push-pull molecules are affected by their arrangement (linear/quadrupolar/tripodal), the peripheral acceptor attached, extension and planarization of the p-system, and also by the type of auxiliary N-substituent.
