Environmental polarity is an important factor that drives biomolecular interactions to regulate cell function. Herein, a general method of using the fluorogenic probe NTPAN-MI is reported to quantify the subcellular polarity change in response to protein

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 N,N′-diphenyl-1,4-phenylenediamine, under mild conditions using Pd(OAc)2 and P(t-Bu)3 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. The fluorescent emission peaks changes at 540 and 580 nm upon grinding were attributed to a transformation from crystal to amorphous occurring by altering the condensed state. The photoluminescence quantum yield and fluorescence lifetime of the as prepared and ground samples were 74.3 and 8.4%, 3.4 and 5.1 ns, respectively. The difference of the luminous efficiency of before and after grinding samples indicates BP2TPAN has a high contrast more importantly, both doped and nondoped OLED devices emit different color, the doped one is highly efficient and its Lmax, CEmax, PEmax and EQE are up to 15070 cd m-2, 11.0 cd A-1, 7.5 lm W-1, and 3.1%, respectively.

To obtain highly efficient blue-violet light conversion agents used for an agricultural film, six triarylacrylonitrile derivatives and their doping films were prepared. Further, the luminogens have the ability to convert ultraviolet light into blue-violet

New triphenylacrylonitrile derivative (DPPA) with triphenylamine moiety as electron donor group has been synthesized. Its emission wavelengths were strongly affected by solvent polarity, indicating intramolecular charge transfer (ICT) transitions. It was found that DPPA was almost non-emissive in tetrahydrofuran (THF), and the emission could be intensified obviously when a great amount of H2O was added, illustrating aggregation induced emission property. It is interesting that the pristine crystal of DPPA emitted green light, and the ground made its emitting color to change into orange, which could be recovered under fumed with dichloromethane (DCM) vapor. The piezofluorochromic behavior might be switched reversibly under the stimulus of external force because of crystalline-amorphous phase transformation, which could be confirmed from the results of PXRD patterns and DSC curves in different solid states. This work might open a new strategy to provide a broad perspective for the development of AIE PFC materials.
Polycarbazoles and polytriphenylamines showing aggregation-induced emission (AIE) and intramolecular charge transfer (ICT) behavior for the optical detection of nitroaromatic compounds

Acceptor-substituted polycarbazoles (PCzTPAN) and polytriphenylamines (PTPATPAN) bearing electron-deficient 2,3,3-triphenylacrylonitrile (TPAN) side groups have been successfully synthesized. Both of them are aggregation-induced emission (AIE)-active and show intramolecular charge transfer (ICT) behavior. PCzTPAN and PTPATPAN aggregates in 90% water/THF were used for the detection of 1,3,5-trinitrobenzene (TNB) as prototypical nitroaromatic compound. They show amplified PL quenching upon addition of TNB with a maximum quenching constant of 5.5 × 105 M-1. As additional application example, the detection of the glass transition temperature of polystyrene (PS) was accomplished for PTPATPAN blended into PS at doping concentrations of 0.1-1.0 wt%.

Synergy between twisted conformation and effective intermolecular interactions: Strategy for efficient mechanochromic luminogens with high contrast
Yuan, Wang Zhang,Tan, Yeqiang,Gong, Yongyang,Lu, Ping,Lam, Jacky W. Y.,Shen, Xiao Yuan,Feng, Cunfang,Sung, Herman H-Y.,Lu, Yawei,Williams, Ian D.,Sun, Jing Zhi,Zhang, Yongming,Tang, Ben Zhong

A strategy towards efficient mechanochromic luminogens with high contrast is developed. The twisted propeller-like conformations and effective intermolecular interactions not only endow the luminogens with AIE characteristics and high efficiency in the crystalline state, but also render them to undergo conformational planarization and disruption in intermolecular interactions upon mechanical stimuli, resulting in remarkable changes in emission wavelength and efficiency.
