Absorption, Fluorescence, and Two‐Photon Excitation Ability of 5‐<i>o</i>‐Tolyl‐11 (or 13)‐<i>o</i>‐tolylisoindolo[2,1‐<i>a</i>]quinolines Prepared by Ring‐Closing Metathesis and [2+3] Cycloaddition
We have successfully improved the fluorescence quantum yield of isoindolo[2,1-a]quinoline derivatives by suppressing the rotation of the phenyl groups at positions 5 and 11 (or 13). Additionally, we found that the planarity of these phenyl groups at positions 5 and 11 (or 13) of isoindolo[2,1-a]quinoline derivatives is crucial for two-photon absorption properties.
