“…Electrochemical studies of iron and ruthenium complexes of L on ITO-30 film (Fe–L/ITO-30 and Ru–L/ITO-30) show good reversibility at all scan rates from 1 to 200 mV/s. The E 1/2 determined at 50 mV/s for Fe–L/ITO and Ru–L/ITO are equal to 0.49 and 0.54 V (vs Fc/Fc + ), respectively, which is consistent with previously reported values for similar complexes in solution , and on a solid support …”

“…Electrochemical studies of iron and ruthenium complexes of L on ITO-30 film (Fe−L/ITO-30 and Ru−L/ITO-30) show good reversibility at all scan rates from 1 to 200 mV/s. The E 1/2 determined at 50 mV/s for Fe− L/ITO and Ru−L/ITO are equal to 0.49 and 0.54 V (vs Fc/ Fc + ), respectively, which is consistent with previously reported values for similar complexes in solution 25,26 and on a solid support. 27 The durability of both Fe−L/ITO and Ru−L/ITO materials is very good and the peak current just insignificantly decreases after 400 cycles compared to the 50 cycle durability test (Figure 2).…”

Novel electrochromic (EC) materials were developed and formed by a two-step chemical deposition process. First, a self-assembled monolayer (SAM) of 2,2':6',2″-terpyridin-4'-ylphosphonic acid, L, was deposited on the surface of a nanostructured conductive indium-tin oxide (ITO) screen-printed support by simple submerging of the support into an aqueous solution of L. Further reaction of the SAM with Fe or Ru ions results in the formation of a monolayer of the redox-active metal complex covalently bound to the ITO support (Fe-L/ITO and Ru-L/ITO, respectively). These novel light-reflective EC materials demonstrate a high color difference, significant durability, and fast switching speed. The Fe-based material shows an excellent change of optical density and coloration efficiency. The results of thermogravimetric analysis suggest high thermal stability of the materials. Indeed, the EC characteristics do not change significantly after heating of Fe-L/ITO at 100 °C for 1 week, confirming the excellent stability and high EC reversibility. The proposed fabrication approach that utilizes interparticle porosity of the support and requires as low as a monolayer of EC active molecule benefits from the significant molecular economy when compared with traditional polymer-based EC devices and is significantly less time-consuming than layer-by-layer growth of coordination-based molecular assemblies.

“…As expected, introduction of an aliphatic chain onto the thiophene ring subsequently lowered the melting point of the product (98-99 • C) when compared to other non-functionalized chalcogenophene-substituted terpyridine molecule [20][21][22][23]. This phenomenon is also observed in an hexylthiophene-functionalized 2,2 :2 ,2"-terpyridine [11] (Table 1).…”

“…Besides the successful integration of terpy into soft materials and polymers, incorporation of this functional component into solid supports is an important step for the creation of materials for molecular electronics and photonics [22], electrochromic materials [23], and solar cells. Terpy motifs have been anchored onto a large number of solid supports resulting in functional materials with enhanced stability and excellent light absorption properties [18,[23][24][25][26][27][28][29].…”

Rational design of a material for rapid colorimetric Fe2+ detection

Wereport on the rational design of a novel TiO2 based screen-printed material suitable for sensitive and selective\ud detection of iron ions in water. This includes the synthesis and characterization of large mesoporous TiO2 nanostructures,\ud screen-printing of thick titania films on glass surfaces and their functionalization with 2,2′:6′,2″-\ud terpyridin-4′-ylphosphonic acid (terpy). The ultra-high affinity between iron ions and the TiO2-anchored terpy\ud receptor makes this system potentially applicable to the analysis of iron in environmental, food, biological, and\ud biomedical systems by a readily quantifiable colour change. Rapid (b30 s) colour change of the material from\ud white to magenta permits easy detection of as low as 0.3 ppm of Fe2+ by the naked eye. The intensity of the colour\ud change depends on the nature of the nanoparticles, the overall TiO2 film thickness, and the Fe2+ concentration.\ud The material was characterized using profilometry, diffuse reflectance UV–vis spectroscopy, and X-ray\ud photoelectron spectroscopy (XPS) before and after treatment with aqueous solutions of Fe2+. The designed material\ud shows colour reversibility upon treatment with EDTA solutions, which allows for multiple reuses of the\ud same film with no effect on sensitivity
