The role of iron (+2 and +3 oxidation states) in biological and medical applications and the environment is pivotal. Supramolecular analytical approaches to monitor and remediate iron, in particular, ferric ions (Fe3+) are an area of interest. The development of fluorescence chemosensors using supramolecular chemistry seems to have exponentially grown since the beginning of the twenty-first century. This article will focus on the chemodosimeter and chemoreactand approach which have been developed to target ferric ions. This review will focus on two broad areas; the first section will discuss the ?traditional? approach, i.e. small molecule recognition, in organic, mixed organic-aqueous and buffer-aqueous solutions. The second section will highlight the molecular sensors that have been either doped or attached to surfaces to prepare nano-chemical sensors.

Six ruthenium(II) complexes have been prepared using the tridentate ligands 2,6-bis(benzimidazolyl) pyridine and bis(2-benzimidazolyl methyl) amine and having 2,2?-bipyridine, 2,2?:6?,2?-terpyridine, PPh3, MeCN and chloride as coligands. The crystal structures of three of the complexes trans-[Ru(bbpH2)(PPh3)2(CH3CN)](ClO4)2 · 2H2O (2), [Ru(bbpH2)(bpy)Cl]ClO4 (3) and [Ru(bbpH2)(terpy)](ClO4)2 (4) are also reported. The complexes show visible region absorption at 402-517 nm, indicating that it is possible to tune the visible region absorption by varying the ancillary ligand. Luminescence behavior of the complexes has been studied both at RT and at liquid nitrogen temperature (LNT). Luminescence of the complexes is found to be insensitive to the presence of dioxygen. Two of the complexes [Ru(bbpH2)(bpy)Cl]ClO4 (3) and [Ru(bbpH2)(terpy)](ClO4)2 (4) show RT emission in the NIR region, having lifetime, quantum yield and radiative constant values suitable for their application as NIR emitter in the solid state devices. The DFT calculations on these two complexes indicate that the metal t2g electrons are appreciably delocalized over the ligand backbone.

“Rollover”-cyclometalated [Pt(bipy – H)]+ (bipy = 2,2?-bipyridine) can be easily generated in the gas phase via HX elimination brought about by collision-induced dissociation (CID) of the cationic complexes [Pt(X)(bipy)]+ with X = CH3, Cl; the latter as well as other [M(X)(bipy)]+ complexes (M = Ni, Pd; X = CH3, F, Cl, Br, I, OAc) are accessible by electrospray ionization mass spectrometry. For the nickel and palladium methyl complexes [M(CH 3)(bipy)]+, upon CID, no cyclometalation occurs; rather, homolytic cleavage of the M-CH3 bond takes place. The related chloro complexes [M(Cl)(bipy)]+ (M = Ni, Pd) undergo competitive eliminations of HCl and Cl upon CID, and the branching ratios depend strongly on the collision energy. On the basis of DFT calculations, this metal- and ligand-controlled behavior is a consequence of the rather different energetic requirements for the direct loss of X versus elimination of HX (X = CH 3, Cl). Deuterium-labeling experiments reveal that formation of CH4 and HCl is only for the platinum complexes due to a genuine “rollover” cyclometalation process, i.e., selective abstraction of a hydrogen atom from the C(3)-position of bipy. In the series of halo-substituted complexes [Ni(X)(bipy)]+ (X = F, Cl, Br, I), the Ni-X bond strength decreases in the sequence F > Cl > Br > I. For X = F, one observes the elimination of HF, which benefits from the particular stability of this molecule; the hydrogen atom in HF is mostly (>90%) abstracted from position C(6) with <10% originating from C(3) of the bipy ligand; thus, for this system "rollover" cyclometalation occurs only to a small amount. [Ni(Cl)(bipy)]+ undergoes competitive losses of HCl and Cl upon collision with Xe, and for X = Br and I only homolytic Ni-X bond cleavage takes place. In the elimination of HCl from [Ni(Cl)(bipy)]+, >60% of the hydrogen atoms originate from C(3), and the remaining from C(4,5,6), as inferred from deuterium-labeling experiments. The acetate complexes [Ni(OAc)(bipy)]+ and [Pd(OAc)(bipy)]+ exhibit eliminations of neutral AcO?, and at elevated collision energies, decarboxylation occurs. C-H bond activation resulting in the formation of HOAc is absent at the detection limit.

A review of papers up to 2008 dealing with all branches of chemistry of the compounds containing 2,2′-pyridine-2,6-diylbis(1H-benzimidazole) and 2,2′-pyridine-2,6-diylbis(1,3-benzothiazole) is presented. The review summarizes the preparation procedures and properties of free organic compounds, as well as their different protonated and/or deprotonated forms. A summary of complex compounds of the considered ligands is presented together with the review of the most important properties such as spectroscopic properties, structures, magnetic properties or biological and electrochemical activity. From this review the blind spots can be identified which might suggest more points of potential interest. Also missing is a promising investigation of, at present unknown, analogues.

A series of Mn(II) halide complexes has been synthesized with 2,6-bis(benzimidazole)-pyridine (BBP), 2,6-bis(N-methyl-benzimidazole)pyridine (MBBP), and 2,6-bis(benzathiazole)-pyridine (BBTP) ligands in solvents capable of acting as hydrogen bonding donors and/or acceptors, resulting in Mn(BBP)(EtOH)X2 (X = Cl, Br), Mn(BBP)Br2·DMF, Mn(BBP)Br2·MeCN, Mn(MBBP)X2 (X = Cl, Br), [Mn(MBBP)(Br)(MeOH)2][Br] and Mn(BBTP)X2 (X = Cl, Br). The crystal structures of these materials were analyzed for the degree of planar packing of the anisotropic ligands. The exchange of hydrogen bonding donor and acceptor solvents (ethanol) for solvents only capable of accepting hydrogen bonds (DMF, acetonitrile) decreased the role of the solvent in the hydrogen bonding networks and also capped the NH groups of BBP, reducing the effectiveness of the BBP to form extended networks. Replacing NH groups in BBP with N-methyl groups (MBBP) and sulfur (BBTP) reduced the number of strong interactions between complexes, leading to a greater tendency for nonplanar crystal packing of the ligands. The effect of poorly oriented anisotropic ligands within the structures results in lower birefringence (Deltan) values of 0.229(10) and 0.23(3) for Mn(BBP)Cl2·DMF and Mn(MBBP)Br2, respectively. Compounds Mn(BBP)(EtOH)X2 (X = Cl, Br) were found to have good stacking of BBP units, leading to a highly anisotropic structure and a Deltan value of 0.538(3) for Mn(BBP)(EtOH)Br2.
