Advances in the field of π-conjugated 2,2′:6′,2″-terpyridines

Abstract

This critical review summarizes the research progress made in the field of π-conjugated terpyridines within the last decade. Supramolecular materials based on metal ion complexes of 2,2':6',2"-terpyridine derivatives have found manifold potential applications-from opto-electronic devices to life science. In this contribution, synthetic strategies towards π-conjugated terpyridines and their incorporation into advanced supramolecular architectures are evaluated. Applications as photoactive species in, e.g., photovoltaic devices, polymer light-emitting diodes (PLEDSs) and nanotechnology are discussed comprehensively (523 references).

“…Polypyridines have attracted much attentions for their high binding affinity toward transition-metal ions,and have awide range of applications in OLEDs, dye-lasers, sensors and phototherapeutic reagents [2][3][4]. During our synthesis of some poly-dentated organic ligands and their metal ions complexes, we got the title compound, and report it structure here.…”

Rational design of a material for rapid colorimetric Fe2+ detection

“…These structures were applied for metal ion sensing [10][11][12], counter anion sensing [8,13,14], sensing of bio-molecules [15,16], and for bio-imaging [17]. Incorporation of terpy derivatives into polymeric matrices often results in the formation of functional materials that can be employed as effective sensors [18]. For example, solutions of polyiminofluorene based polymer decorated with terpy groups were utilized as a highly sensitive and specific fluorimetric zinc sensor in organic solvent media [10].…”

“…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]. Nishihara et al have achieved long range electron transport for molecular electric wires by assembling bis(terpyridine) metal complexes on gold surfaces.…”

Synthesis of Metallo-Supramolecular Polymers with Bis-NNN-Tridentate Ligand for Electrochromic Devices

“…Metallo-supramolecular polymers have recently received much attention as a new type polymer in which the polymer backbone is formed by coordination bonds [1][2][3][4]. The electronic interaction between the metal ion and the ligand through the coordination bonds causes unique properties.…”
