| Research Abstract |
In this work, novel polycyanide building blocks were designed and synthesized. Polycyanide building units can be modified by the introduction of functional supporting ligands and novel extended polycyanide systems can be developed by the reaction of polypyridine type ligands with iron sources and cyanide ions. Thus, the reactions of various polypyridine ligands, iron sources and cyanide ions were investigated. When 2,4,6-tris-(2-pyrimidyl)-1,3,5-triazine (L1) was used, the tricyanide building unit, K[Fe(L1)(CN)3], was synthesized. One-dimensional chain compounds were formed by the reaction of K[Fe(L1)(CN)3] and iron sources. When the luminescent ligand 2-(1H-Benzoimidazol-2-yl)-pyridin-3-ol (L2) was used, the tetracyano building unit, K3[Fe(L2)(CN)4], was obtained. These results suggest that functional polypyridine ligands can be used to form useful polycyano building units.
