- Abstract
1,3a,6a‐Triazapentalene (TAP) is a compact fluorescent molecule consisting of a triazabicyclo[3.3.0]octane skeleton. In this work, a method of synthesizing a directly connected TAP ring system as a linearly bonded aromatic system with a planar form was established. The TAP‐bonded system showed interesting fluorescence properties resulting from changes in aggregation state at high concentration and solid state. In particular, solids of some TAP‐bonded systems showed changes in fluoresence color by grinding, that is, typical mechanochromic fluorescence properties were observed. The cover picture shows that fluorescence is emitted when the DJ scrapes the TAP‐bonded system represented by disks. More information can be found in the Full Paper by K. Namba et al. on page 17727.
