New cyclic germanium element‐block materials have been synthesized. Arene‐inserted extended (ArEx) germa[ n ]pericyclynes composed of germylene, diyne, and phenylene units showed unique and highly improved UV absorption and fluorescence emission characteristics compared to previous germapericyclynes. Even in the absence of transition metal components, phosphorescence emissions with long lifetimes were observed. Moreover, ArEx germapericyclynes showed high photoluminescence quantum yields, whereas those of acyclic compounds were low. More information can be found in the Full Paper by H. Tanimoto, K. Kakiuchi et al. on page 10080.
