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, tha… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
