non-phosphorescent guest exhibits a 2.62 s ultralong lifetime after being complexed by CB[6] under ambient conditions. The ultralong RTP is because of tight encapsulation of CB[6], which boosts intersystem crossing, suppresses nonradiative relaxation and possibly shields quenchers. Moreover, several phosphorescent complexes possessing different lifetimes are prepared and successfully applied in triple lifetime-encoding
Oligo-p-phenylenes have proven to be versatile building blocks for the generation of self-assembled nanoaggregates via vapour deposition on solid supports whose optical properties and morphologies can be influenced by the introduction of functional groups. These aggregates show strong polarized luminescence and they have been demonstrated to have wave-guiding, lasing and even non-linear optical properties (e.g., frequency doubling) when the molecular building blocks are suitably functionalized. Thus, there is a demand for the synthesis of further functionalised p-phenylenes because similar properties can be expected from derivatives incorporating heteroaryl groups in the oligoarylene scaffold such as thiophenes, pyridines or carbazole units. The synthesis of such derivatives using a reliable Suzuki cross-coupling strategy is presented here.
