A simple strategy to modulate the singlet-triplet energy gap in 3,6-diaryl--acetophenylcarbazole derivatives is developed. Different substituents significantly influenced Δ, which is correlated for the first time with the singlet-triplet state dipole moments. Phosphorescence at ambient conditions in powder form ( is up to 248 μs) and ultra long lifetime (up to 2.2 s) at 77 K is observed.
