AIE-active polyanetholesulfonic acid sodium salts with room-temperature phosphorescence characteristics for Fe detection.

Room-temperature phosphorescent materials have been a major focus of research and development during the past decades, due to their applications in OLEDs, photovoltaic cells, chemical sensors, and bioimaging. However, achieving polymeric phosphorescent materials without heavy-metal atoms and halogens under ambient conditions remains a major challenge. Here, we report a polymeric phosphor, namely polyanetholesulfonic acid sodium salt, which not only has room temperature phosphorescence characteristic but also aggregation-induced emission and dependence on the excitation wavelength characteristics.

A novel triphenylacrylonitrile based AIEgen for high contrast mechanchromism and bicolor electroluminescence.

A novel thermally stable and aggregation-induced emission (AIE) active compound, 2,2'-(([1,1'-biphenyl]-4,4'-diylbis(phenylazanediyl))bis(4,1-phenylene))bis(3,3-diphenylacrylonitrile) (BP2TPAN) was synthesized through a C-N coupling reaction between 2-(4-bromophenyl)-3,3-diphenylacrylonitrile (Br-TPAN) and ,'-diphenyl-1,4-phenylenediamine, under mild conditions using Pd(OAc) and P(-Bu) as a catalyst. The BP2TPAN was characterized by nuclear magnetic resonance spectroscopy, high resolution mass spectrometry and elemental analysis. The thermal analysis showed that the glass transition and decomposition temperatures (5% weight loss) are 96 and 414 °C, respectively.
