Cover Picture: Intramolecular Triple Cyclization Strategy for Sila‐ and Oxa‐Analogues of Truxene with Long‐Lived Phosphorescence (Asian J. Org. Chem. 3/2017)

Ninja power: The picture represents C3-symmetric structures of truxene and its sila- and oxa-analogues as "Shuriken", which is a traditional star-shaped throwing weapon used by a "Ninja", a covert agent in feudal Japan. The "Shuriken" pierces C, Si, and O elements in the periodic table on the board. All of the synthesized truxenes display long-lived phosphorescence with lifetimes in the range of 4.4–16.4 s.
