Synthesis and photophysical properties of new ?,?-bis(tpy)oligothiophenes and their metallo-supramolecular polymers with Zn2 ion couplers

Popis výsledku v původním jazyce

Five new ?,?-bis(tpy)bithiophenes and terthiophenes, each comprising two hexyl groups attached to oligothiophene block at different positions, were prepared using the Suzuki coupling strategy, characterized (NMR, IR, Raman, HRMS, UV/vis, fluorescence, cyclic voltammetry) and transformed to corresponding conjugated metallo-supramolecular polymers with Zn2+ ion-couplers. Reference oligomers with unsubstituted central blocks and their polymers are also reported. Photophysical properties of oligomers and polymers are described, analyzed with a help of DFT calculations, and correlated with the chemical constitution of oligomeric building blocks. Steric effects were shown to exceed the electronic effects of hexyl groups, and twisting the thiophene-thiophenebonds were shown to influence electronic spectra of oligomers and polymer more deeply than twisting the thiophene-tpy bonds. Outlying photoluminescence characteristics observed for some oligomers and polymers were shown to be consistent w
