      Food Control. 122, 107816 (2021). HPTLC of histamine in fish samples on a silica gel read-out strip coated with a ninhydrin@TiO2 complex (0.1 M titanium butoxide and 5 % ninhydrin as precursors) as self-visualization nanomaterial in the histamine target zone (hRF value of 24). Samples were developed using n-butanol - acetone - ammonia 20:5:2. Detection after heating at 80 °C for 30 s. Linearity was between 15 and 320 mg/kg. The LOD for histamine was 5 mg/kg.

      Utilization of a crown ether/amine‐type rotaxane as a probe for the versatile detection of anions and acids by Thin‐Layer Chromatography.
      S. MIYAGAWA, M. KIMURA, S. KAGAMI, T. KAWASAKI, Y. TOKUNAGA* (*Department of Materials Science and Engineering, University of Fukui, Bunkyo, Fukui, Japan; tokunaga@u-fukui.ac.jp)

      Chem. Asian J. 15(19), 3044-3049 (2020). The studied rotaxane combines a dibenzocrown of 8 ethers (DB24C8) with an axle chain (Ax) containing two amines, one of them in an aniline group, allowing stability of the rotaxane even when the other one is unprotonated. TLC on silica gel in 4 steps, with detection under UV light or after derivatization with phosphomolybdic acid in ethanol. (1) Before the synthesis of the rotaxane, unprotonated Ax was isolated by preparative TLC of the protonated Ax obtained by addition of HCl or toluenesulfonic acid (TsOH); the mobile phases were chloroform – methanol 10:1 and toluene – tetrahydrofurane 3:2, respectively. The isolated molecules were confirmed as totally unprotonated Ax by NMR, suggesting a complete loss of HCl and TsOH on the silica gel layer. (2) After synthesis, unprotonated rotaxane, pure vs. monoprotonated by the addition of 10 different acids (and purified by column chromatography CC), was applied on TLC plates and developed with dichloromethane – acetone – water 3:16:1; the hRF values were very different, depending on the counter-anions from the used acids. (3) The same behavior (except with sulfuric acid) was observed under the same conditions when CC was omitted (unprotonated rotaxane samples were mixed with each of the acids, or with two acids at the same time for acid-competitive TLC analysis). (4) When unprotonated rotaxane was applied under the same conditions as in step (3) with the sodium salts instead of the acids, the behavior was similar (except for the shapes of the spots, due to the salts in excess). The rotaxane can thus be used for the TLC separation and detection of sodium salts, by forming salts of protonated rotaxane with the anion afforded by these sodium salts. The rotaxane protonation seems to be promoted by the methanol of the spotting mixture; indeed, when step (3) was performed with the mobile phase chloroform – methanol 10:1, a second zone appeared because methanol formed a salt with the rotaxane (identified by NMR).
