Gonzalez-Rodriguez, Edgar;Guzman-Juarez, Brenda;Miranda-Olvera, Montserrat;Carreon-Castro, Maria del Pilar;Maldonado-Dominguez, Mauricio;Arcos-Ramos, Rafael;Farfan, Norberto;Santillan, Rosa research published 《 Effect of the π-bridge on the light absorption and emission in push-pull coumarins and on their supramolecular organization》, the research content is summarized as follows. A family of eight π-extended push-pull coumarins with cross-conjugated (amide) and directly conjugated (p-phenylene, alkyne, alkene) bridges were synthesized through a convergent strategy. Using an exptl. calibrated computational protocol, their UV-Visible light absorption and emission spectra in solution were investigated. Remarkably, amide-, alkyne- and alkene-bridges undergo comparable vertical excitations. The different nature of these bridges manifests during excited-state relaxation and fluorescence. These mols. can serve as building blocks for p-type semiconductors with low reorganization energies, below 0.2 eV. Since solid-state self-assembly is crucial for this application, the effect of the π-bridge over the supramol. organization in this family of compounds was examined to determine if stacking prevails in these π-extended coumarin derivatives Amide and alkyne spacers allow coplanar conformations which crystallize readily; p-phenylene hinders planarity yet allows facile crystallization; alkene-bridged mols. eluded all crystallization attempts. All the crystals obtained feature dense face-to-face π-stacking with 3.5-3.7 Å interlayer distances, expected to facilitate charge transfer processes in the solid state.
