Syntheses of heterotriptycenes and their Pt complexes that emit circularly polarised fluorescence and phosphorescence

Herein, we report the synthesis and chiroptical properties of 2-azatriptycenes and their platinum( ii ) complexes, which represent the first examples of heterotriptycenes and metallotriptycenes that exhibit circularly polarized fluorescence and phosphorescence (CPF and CPP). Theoretical studies for CPF and CPP strongly support the experimental findings. Optically active 2-azatriptycenes and their platinum( ii ) complexes were synthesized. The molecules could be employed as efficient emitters exhibiting circularly polarized fluorescence and phosphorescence.
