- •
Fluorene-carbazole triads showed high emission quantum yield and radiative decay rate.
- •
The triads expressed low amplified emission threshold and high carrier mobility.
- •
Low concentration quenching of emission ensured low ASE threshold at high concentrations.
- •
Advantage of 2,7- substitution pattern vs 3,6- for light amplification is demonstrated.
- •
Trade-off between ASE threshold and carrier mobility of the triads is revealed.
