A new Λ-shaped α-cyanostilbene derivative (TSA) containing an active amino group with fluorescence emission both in solution and the solid state was designed, synthesized and characterized. Its colour and fluorescence emission can be switched by external stimuli including acid/base, trinitrophenol (picric acid, PA) and grinding. The 1H NMR spectra of TSA were recorded before and after alternately adding trifluoroacetic acid (TFA) and triethylamine (TEA), which confirmed that acidichromism originated in the transformation of protonation/deprotonation between TSA and TSA-H+. Powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) revealed the crystalline-amorphous state transformation between the original and ground compounds, and this transformation could reasonably account for the mechanochromic (MFC) luminescence properties. The results revealed that TSA can be used as a fluorescence sensor for acid/base and PA, and as a rewritable information storage material. Moreover, it can also be applied in white light-emitting diodes (w-LEDs) based on its desirable fluorescence emission in the solid state.

Two molecular rotors with a single excitation and dual-color emission wavelengths were engineered for simultaneous imaging of lysosomal and mitochondrial viscosity. These two molecular rotors were highly sensitive to viscosity without dependence on pH or polarity, facilitating simultaneous imaging of lysosomal and mitochondrial viscosity during mitophagy in living cells.

The host-guest interaction of trans-4-[4-(dimethylamino)styryl]-1- methylpyridinium iodide (DSMI) with cucurbit[7]uril (CB[7]) was investigated through fluorescence, absorption, 1H NMR and mass spectrometry. DSMI can be included by CB[7] with 1:2 stoichiometry to form the DSMI/CB[7] complex, exhibiting a larger binding affinity than that of DNA. To make a comparison with DSMI, another pyridium vinyl group was introduced into the aniline ring of DSMI to get a hemicyanine derivative D2, and a ternary complex among D2, CB[7] and DNA was formed. All these provide new insights to investigate the interaction of organic dyes, CB[7] and DNA.
