The incorporation of aggregation-induced emission (AIE) luminogens provides a molecule with enhanced fluorescent emission in the solid state. A representative AIEgen compound is tetraphenylethene (TPE). A series of new conjugates of quinolone derivatives with TPE units (1a - 1f) was synthesized and characterized. The influence on the photophysics of 1a - 1e with a variety of functional groups was investigated systematically by spectroscopic methods and simulated by density-functional theory calculations. A centrosymmetric compound donor-acceptor-donor-type compound 1f with two TPE moieties proved to be the most promising multifunctional material, it exhibited tri-colored (489–569 nm) fluorescence characteristics in tetrahydrofuran-H2O solution with a different water fraction and intense tri-colored solvatochromic (blue, green, and yellow) behaviors. These compounds could be applied as promising acid-base gas probe based on their evident color switch. Compounds 1a - 1f showed the advantage of being a potential piezochromic material.

supporting information; experimental part, p. 4704 - 4711 (2012/08/08)
A series of triphenylamine-centered starburst quinolines (1a-1g) have been synthesized by Friedlaender condensation of the 4,4′,4′′- triacetyltriphenylamine (2) and 2-aminophenyl ketones (3a-3g) in the presence of catalytic sulfuric acid and characterized well. They are thermally robust with high glass transition temperatures (above 176.4 °C) and decomposition temperatures (above 406 °C). These compounds emit blue fluorescence with λEmmax ranging from 433 to 446 nm in dilute toluene solution and 461 to 502 nm in the solid-state and have a relatively high efficiency (Φu = 0.98-0.57). 1a-1g have estimated ionization potentials (IP) of 4.54 to 6.45 eV which are significantly near or higher than those of well-known electron transport materials (ETMs), including tris(8- hydroxyquinoline)aluminium (Alq3) (IP = 5.7-5.9 eV), and previously reported oligoquinolines (IP = 5.53-5.81 eV). Quantum chemical calculations using DFT B3LYP/6-31G* showed the highest occupied molecular orbital (HOMO) of -5.05 to -4.81 eV, which is close to the work function of indium tin oxide (ITO). These results demonstrate the potential of 1a-1g as hole-transporting/light-emitting/electron-transport materials and the host-materials of a dopant for hole-injecting for applications in organic light-emitting devices.
