Multi-emission regulation of trans-4-[4-(N,N-dimethylamino)styryl]pyridine with a mild host-guest strategy based on H-type β-zeolite

A dysprosium(iii)-based triple helical-like complex as a turn-on/off fluorescence sensor for Al(iii) and 4,5-dimethyl-2-nitroaniline

“…S10†), the electron-pulling ability of the acceptors was promoted after protonation, enhancing the intramolecular charge transfer together with the red-shifted emissions. 44 On the contrary, a blue shift occurred under alkaline conditions (pH = 10–14, Fig. S10†).…”
