Azaacene diradicals based on Non-Kekulé meta-quinodimethane with large two-photon cross-sections in the infrared spectral region
Non-Kekulé quinoidal azaacences m-A (1a,b) were synthesized and compared to their para- and ortho-quinodimethane analogues. m-Adisplay high diradical characters (1b: y0 = 0.88) due to their meta-quinodimethane (m-QDM) topology. Electron paramagnetic, nuclear magnetic resonance spectroscopies and su...
