Three kinds of ionochromic dye were used to dye silk fabric, and they were evaluated for colour changes triggered by Fe(II) solution. The K/S values and photos of the fabrics were then recorded. It was found that 1,10-phenanthroline was the most suitable ionochromic dye in these dyes. Colour change from white to red could be clearly seen when 1,10-phenanthroline-dyed silk fabric was triggered by Fe(II) solution, but it showed no colour change when triggered by Cu(II), Mg(II), or Ca(II) solution. Moreover, 1,10-phenanthroline-dyed nylon, polyester, and cotton fabrics showed no obvious colour changes after triggering by Fe(II) solution. Ion concentration, pH value, and reaction time could affect the colour changes. When triggered by 8 mg l?1 of Fe(II) solution at neutral pH for about 15 min, the ionochromic fabric showed a clear colour change. In addition, three coloured fabrics in green, blue, and yellow were also dyed with 1,10-phenanthroline. It was found that they could also show clear colour changes when triggered by Fe(II) solution. These ionochromic fabrics may find broad application in many fields, such as Fe(II) detection, magic toys, anticounterfeiting materials, and bionic silk flowers.

Sondes fluorescentesIndex. décimale : 535.6 Couleur Résumé : Two isomeric proton–receptor fluorescent probes 1 and 2 were designed and synthesised by employing the photoinduced electron transfer (PET) principle of a ‘fluorophore–spacer–receptor’ module. Their photophysical characteristics were investigated in organic solvents and Britton–Robinson buffer/EtOH (1:1, v/v) solution. Probe 1 was sensitive in the stronger acidic region of 2.21–4.56, while probe 2 displayed a good response towards protons within the pH scope of 4.10–6.09. The specificity of the probes toward protons in commonly used buffer solutions and in the presence of metal cations, Na(i), K(i), Ca(ii), Mg(ii), Al(iii), Pb(ii), Fe(iii), Ni(ii), Zn(ii), Cu(ii), Hg(ii), Ag(i), Co(ii), Cr(iii), Mn(ii), and Cd(ii) ions, was studied by monitoring the changes in their fluorescence intensity. The tested metal ions exerted no noticeable influence. The results obtained show that the synthesised proton–receptor fluorescent probes have the capability to act as pH-sensitive probes for monitoring pH variations in the range 2.21–6.09.
