“…In the crystal structure of L , occupational disorder between bromine and chlorine was found on the halogen position. The position of the halogen site was partially occupied by bromine (66.3% occupancy) and chlorine (33.7% occupancy). − The torsion angles between the central imidazole ring and two phenyl rings were found to be 89.2 and 100.6°. The phenylpyridyl moieties are significantly nonplanar, as is evident from the dihedral angles of 28.1 and 29.1° involving the terminal pyridyl rings and phenyl spacer.…”

A Functional Zn(II) Metallacycle Formed from an N-Heterocyclic Carbene Precursor: A Molecular Sensor for Selective Recognition of Fe³⁺ and IO₄^– Ions

We have reported the synthesis and structural characterization of a unique Zn(II) metallacycle (1) and its utilization as a fluorescent probe for the shape-specific selective recognition (turn-off) of Fe and IO ions. The relevant Stern-Volmer graphs indicate that the recognitions of Fe and IO ions are examples of diphasic and monophasic quenchings, respectively. The title metallacycle has been prepared by the reaction of a novel N-heterocyclic carbene precursor, 1,3-bis(2,6-diisopropyl-4-(pyridin-4-yl)phenyl)-1H-imidazol-3-ium chloride/bromide (L), and zinc(II) chloride salt. Notably, the ligand itself did not show any type of recognition for any ions. DFT calculations were performed on L and metallacycle 1 using the geometric parameters, obtained from their single-crystal X-ray diffraction data, to understand the electronic structures of the ligand and macrocycle. The detection limit for the recognition of the Fe ion was determined to be 2.5 × 10 mol/L, and that for IO ion was found to be 6.3 × 10 mol/L.

“…The PAMAM dendrimers were found to be superior, by showing a higher reaction rate and a higher linear/branched ratio, in the cross coupling reaction between vinyl epoxide and styrylboronic acid. In the auto-tandem catalysis of cynnamyl chloride, hexamethylditin, and 4-nitrobenzaldehyde, only small differences were observed in the efficiency of both families of dendrimers [ 27 ]. The effect of PAMAM dendrimers and of triazine dendrimers of comparable size and number of terminal functions, both families being capped with primary amines, was tested toward platelet aggregation, in human platelet-rich plasma.…”

Among the six Critical Nanoscale Design Parameters (CNDPs) proposed by Prof. Donald A. Tomalia, this review illustrates the influence of the sixth one, which concerns the elemental composition, on the properties of dendrimers. After a large introduction that summarizes different types of dendrimers that have been compared with PolyAMidoAMine (PAMAM) dendrimers, this review will focus on the properties of positively and negatively charged phosphorhydrazone (PPH) dendrimers, especially in the field of biology, compared with other types of dendrimers, in particular PAMAM dendrimers, as well as polypropyleneimine (PPI), carbosilane, and p-Lysine dendrimers.

Synthesis of Non‐Symmetric Ruthenium(II) POCOP Pincer Complexes and Their Bimetallic Derivatives by π‐Coordination of Arenophile Fragments

A series of neutral 16-electron square pyramidal ruthenium(II) complexes of the general formula [Ru(POCOP)-(X)(CO)] (X = Cl, H) have readily been obtained in good yields from [RuCl 2 (COD)] n and different POCOP pincer ligands based on the naphthoresorcinate backbone. The molecular structure of two of the compounds was unequivocally determined by single-crystal X-ray diffraction, showing different stereochemistries upon the coordination of chloride or hydride ligand.
