Abstract

Keywords Coordination polymers Metaleorganic frameworks Multidentate ligands Polypyridyl ligands Porphyrin arrays Supramolecular assemblies a b s t r a c tThis review covers the rich coordination chemistry of 2,4,6-tri(pyridyl)-1,3,5-triazine ligands. These polypyridyl derivatives have been coupled to transition metals and lanthanides, and the complexes obtained have been used in various fields such as luminescent materials, for the preparation of coordination polymers and networks as well as for the synthesis of discrete metalla-assemblies. The synthetic and structural aspects of the different isomers of 2,4,6-tri(pyridyl)-1,3,5-triazine are presented, and a survey of their coordination chemistry is given.

Preparation, Crystal structure and Luminescence Properties of Lanthanide Complexes with 2,4,6-tri(pyridin-2-yl)-1,3,5-triazine and Organic Carboxylic Acid

“…Because of the distinctive coordination modes and conjugated large π system, neutral ligand 2,4,6-tri(pyridin-2-yl)-1,3,5-triazine (TPTZ) has become one of the most attractive ligands. Moreover, TPTZ can increase the chemical and thermal stability of the complexes [9][10][11][12][13][14]. In addition, the triplet energy level of TPTZ (21,200 cm −1 ) matches the lowest excited state energy level of Eu 3+ (17,200 cm −1 ), which results in the enhancement of the luminescence intensities of europium…”

Modulating the Binding of Polycyclic Aromatic Hydrocarbons Inside a Hexacationic Cage by Anion–π Interactions

“…Lett. 2004, 6, 4167 -4170;b) , out of the 33456 reflections measured, 5197 were unique (R int = 0.1011, Rs = 0.0729) and were used in all calculations. The final R1 was 0.0931 (I > 2s(I)) and wR2 was 0.3099 (all data); b) for the criteria used to define anion-p distances in coronene&BlueCa-ge·6 PF 6 The ins and outs: A hexacationic macrobicyclic receptor comprised of pyridinium units fused together by electron-poor triazine rings has been shown to be a good receptor for polycyclic aromatic hydrocarbons.…”

Synthesis and Study of 1,2,4-Triazine and Thiadiazoles Based Derivatives of S-Triazine as Antimicrobial Agents

“…In this context, s-triazine scaffold has attracted the attention of many researchers for its therapeutic potential [1] and ease of functionalization on it [2,3]. For example, these compounds possess potent antiprotozoal [4] antimalarial [5,6] antiviral [7][8][9] anticancer [10,11] antimicrobial [12][13][14] anti-tuberculosis [15,16].…”
