Twistacene-modified heteroarenes: synthesis, characterization and optical limiting response
A series of novel twistacene-decorated arenes including heterorings (2, 5, 8) were con-veniently synthesized promoted by palladium catalyst in one step and characterized. Compared with the model twistacene 1, all of them exhibited red-shifted absorption spectra with the maximum peaks centered at 462 nm for 2, 478 nm for 5, 468 nm for 8, and emission spectra spectra with the maximum bands at 476/506 nm for 2, 497/527 nm for 5, 497/520 nm for 8 respectively, which belonged to blue and green fluorescence region. The electrochemical properties were carried out through cyclic voltammetry method and molecule 8 displayed a smallest oxidation potential at 0.35 V among them, which resulted from the oxidation of the amine moiety. Their optical limiting properties were examined via femtosecond laser. The results suggest that all of them exhibit high transmittance and 5 possesses excellent optical limiting response.
