Phosphorescent columnar hybrid materials containing polyionic inorganic nanoclusters

The ternary polyionic inorganic compound Cs2Mo6Br14 and 18-crown-6 ethers bearing two o-terphenyl units have been combined to design phosphorescent columnar liquid crystalline hybrid materials. The obtained host-guest complexes are very stable even at high temperatures. Depending on their surroundin...

Zusammenfassung:The ternary polyionic inorganic compound Cs2Mo6Br14 and 18-crown-6 ethers bearing two o-terphenyl units have been combined to design phosphorescent columnar liquid crystalline hybrid materials. The obtained host-guest complexes are very stable even at high temperatures. Depending on their surrounding atmosphere, these hybrids switch reversibly from a high-to-low luminescence state and show a very stable emission intensity up to 140 °C.
