Category: triazoles. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 6-Methylnicotinic acid, is researched, Molecular C7H7NO2, CAS is 3222-47-7, about Versatile {Cp2Ti} Grafted Hetero-Polyoxotungstate Clusters: Synthesis, Crystal Structure, and Photocurrent Properties.

Polyoxotungstate supported titanocene {Cp2Ti}2+ clusters H6{K8(Cp2Ti)2P4W24O88(PO4)2}·14H2O (1), H6[Na2P4W14O58(Cp2Ti)2]·12H2O (2), and H2[K6{Cp2Ti}{PW9O33(WO2)}2{NC5H3(COOK)2}(NC5H3(CH3)COOK)·22H2O] (3) have been synthesized, and their single crystal x-ray structures have revealed unprecedented and intriguing structural features. The synthesized compounds have been characterized by various spectroscopic techniques including UV-vis, cyclic voltammogram, NMR, ESI-MS, and inductive coupled plasma spectroscopy (ICP) in solution and also by IR, TGA, and diffuse reflectance in the solid state. Clusters 1 and 2 are rare examples of lacunary POM supported titanocene clusters obtained by incorporating various phosphorus heteroatoms to form elusive phosphotungstate assemblies, whereas 3 is an unprecedented organometallic as well as heteroleptic pyridyl functionalized POM. Clusters 1-3 show transient photocurrent ON/OFF behavior upon UV-light irradiation and also exhibit characteristic TiIV/III intravalence electron transfer. This behavior is also established by their cyclic voltammograms in mixed phosphate buffers (Na2HPO4/NaH2PO4) which show the evidence of POM supported {Cp2Ti}2+/+ species in their redox solution Furthermore, ESR line broadening is also observed in these clusters at room temperature, a fact which also confirms the formation of partially reduced/oxidized {Cp2Ti}2+/+ species leading to TiIV/III intravalence electron transfers within all three clusters. The {Cp2Ti}2+ decorated polyoxometalate cluster 3 shows improved transient photocurrent behavior which may be due to the presence of pyridyl carboxyl ions which provide better surface contact for the cluster mol. through the carboxylate moiety to the ITO electrode.
