Tetraazacoronenes were synthesized from bay-functionalized tetraazaperylenes by Zr-mediated cyclization and four-fold Suzuki-Miyaura cross coupling. The use of bis(pinacolatoboryl)vinyltrimethylsilane as a C-2 building block resulted in the desired tetraazacoronene target compound, along with the condensed azacoronene dimer and higher oligomers. The extended azacoronenes exhibited highly resolved UV/Vis absorption bands with increased extinction coefficients for the aromatic cores and fluorescence quantum yields of up to 80% at 659 nm.
Tetraazacoronenes were synthesized from bay-functionalized tetraazaperylenes by Zr-mediated cyclization and four-fold Suzuki-Miyaura cross coupling. In the Zr-mediated approach, an & eta;(4)-cyclobutadiene-zirconium(IV) complex was isolated as an intermediate to cyclobutene-annulated derivatives. Using bis(pinacolatoboryl)vinyltrimethylsilane as a C-2 building block gave the tetraazacoronene target compound along with the condensed azacoronene dimer as well as higher oligomers. The series of extended azacoronenes show highly resolved UV/Vis absorption bands with increased extinction coefficients for the extended aromatic cores and fluorescence quantum yields of up to 80 % at 659 nm.
