文摘
- •
A series of bipyrrole BF2 complexes were synthesized by Sonogashira couplings.
- •
The π system was extended by addition of one or more substituted alkyne units.
- •
Bathochromic emission maxima were observed with ∼10-nm increments.
- •
The photoluminescence quantum yields ranged from 0.35 to 0.83 in dioxane.
- •
Highly emissive character was found both in solution and in the film/solid state.
