dc.description.abstract |
A series of novel V-shaped quinoxaline, [1,2,5]oxadiazolo[3,4-b]pyrazine and [1,2,5]thiadiazolo[3,4-b]pyrazine push-pull derivatives with 2,4 '-biphenylene linker were designed and their electrochemical, photophysical and nonlinear optical properties were investigated. [1,2,5]Oxadiazolo[3,4-b]pyrazine is the stronger electron-withdrawing fragment as shown by electrochemical, and photophysical data. All compounds are emissive in a solid-state (from the cyan to red region of the spectrum) and quinoxaline derivatives are emissions in DCM solution. It has been found that quinoxaline derivatives demonstrate important solvatochromism and extra-large Stokes shifts, characteristic of twisted intramolecular charge transfer excited state as well as aggregation induced emission. The experimental conclusions have been justified by theoretical (TD-)DFT calculations. |

Byla připravena série nových push-pull derivátů na bázi chinoxalinu, [1,2,5]oxadiazolo[3,4-b]pyrazinu a [1,2,5]thiadiazolo[3,4-b]pyrazinu s 2,4 '-bifenylenovým linkerem a byly studovány jejich elektrochemické, fotofyzikální a nelineárně optické vlastnosti. Experientální výsledky byly porovnány s teoretickými DFT kalkulacemi. |
