In this paper, we have designed and synthesized a novel sensor L1 based on asymmetric double-azine derivatives, which showed both “naked eye” recognition and fluorescence responses for CN? in DMSO/H2O (v/v?=?4:1, pH?=?7.20) solution. This simple sensor L1 could distinguish CN? from coexisting anions via the way of deprotonation and sensing mechanism of intramolecular charge transfer (ICT), and the minimum detection limit on fluorescence response of the sensor L1 towards CN? was down to 9.47?×?10??7?M. Moreover, we have successfully utilized the sensor L1 to detect CN? in bitter almond. Test strips containing L1 were also prepared, which could act as a practical colorimetric tool to detect CN? in aqueous media.

Three salicylaldehyde Schiff base (SSB), iso-PBP, PBP and EPB, were facilely synthesized and exhibited aggregation-induced emission. The introduction of C = N-N = C moiety in these SSB dyes largely extend the conjugation system and push their emission to yellow to red spectral region. These SSB dyes were negligibly fluorescent in dilute THF solution. In THF/water mixtures with high water fractions, they displayed strong yellow to red fluorescence (up to 617 nm) and large Stokes shifts (up to 152 nm). Single crystal analysis on EBP showed the longer emission of in aggregated state was attributed to the molecular packing effect as compared with that in dilute solution. The bio-imaging application indicated EBP could specifically accumulate in lipid droplets in living cells.

Different novel symmetric Schiff bases were synthesized in a simple and environmentally benign method from the reaction of produced Schiff base with various aldehydes and ketones using montmorollonite KSF clay as heterogeneous solid acidic catalyst in goo
