“…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).…”

“…[29] Similarly, Husson et al functionalized a Ru(II)-(terpy) 2 complex 14 with tellurophene unit to perform oxidative electropolymerization on different substrates (Figure 8, b). [30] On the other hand, Abruna and co-workers had previously used reductive routes to electropolymerized a vinyl substituted terpyridine and Ru(II)-based metal complex 15 on the electrode surface (Figure 8, c). [31] Similarly, Meyer and co-workers utilized the same system 15 with Fe(II) metal ion and effectively electropolymerized on a nanocrystalline TiO 2 surface (Figure 8, c).…”

Molecular assembly induced by metal-terpyridine-based coordinative interactions has become an emergent research topic due to its ease of synthesis and diverse applications. This article highlights recent significant developments in the metal-terpyridine-based supramolecular architectures. At first, the design aspect of the molecular building blocks has been described, followed by elaboration on how the ligand backbone plays an important role for achieving different dimensionalities of the resulting assemblies which exhibit a wide range of potential applications. After that, we discussed different synthetic approaches for constructing these assemblies, and finally, we focused on their significant developments in three specific areas, viz., electrochromic materials, catalysis and a new application in wastewater treatment. In the field of electrochromic materials, these assemblies made important advancements in various aspects like sub-second switching time (< 1 s), low switching voltage (< 1 V), increased switching stability (> 10000 cycles), tuning of multiple colors by using multimetallic systems, fabrication of charge storing electrochromic devices, utilizing and storing solar energy etc. Similarly, the catalysis field witnessed application of the metal-terpyridine assemblies in CÀ H monohalogenation, heterogeneous Suzuki-Miyaura coupling, photocatalysis, reduction of carbon dioxide, etc. Finally, the environmental application of these coordination assemblies includes capturing Cr(VI) from waste water efficiently with high capture capacity, good recyclability, wide pH independency etc.

[15][16] Among the others, ECDs based on polypyridine metal-coordination complexes demonstrate enhanced cyclic stability, short switching times and exceptional coloration efficiency. Previously, it was demonstrated that 2,2':6',2''terpyridine (terpy) moiety can form stable complexes with a variety of metals in different oxidation states.…”

The paper reports a general methodology for the rational tuning and optimization of electrochromic devices (ECDs) that are based on a monolayer of Fe (II) (4'-(4-pyridyl)-2,2':6',2"terpyridine) 2 complex (Fe 4'T) covalently embedded onto a screen-printed high-surface area indium tin oxide working electrode. We demonstrate that the nature of the counter electrode and the resulting device configuration could drastically improve the long-term stability of the ECD. We show that the replacement of the flat ITO glass electrode with a high surface area ITO electrode or the use of symmetrical working and counter electrode architecture leads to a much longer performance of the device. We propose a methodology to determine optimal operating conditions for ECDs by fine-tuning the lower and upper operation potentials. In addition to using traditional cyclic voltammetry (CV), we utilize electrochemical impedance spectroscopy (EIS) to study the intrinsic properties of the devices and understand the factors that define the longterm cycling stability, which is further described through the use of equivalent circuit models. The main reasoning behind decomposition processes in ECDs and ways to suppress them are discussed.
