Article
Here, we report an approach to the synthesis of highly charged enantiopure cyclophanes by the insertion of axially chiral enantiomeric binaphthyl fluorophores into the constitutions of pyridinium‐based macrocycles. Remarkably, these fluorescent tetracationic cyclophanes exhibit a significant AIE compared to their neutral optically active binaphthyl...

Triplet excited-state organic chromophores present countless opportunities for applications in photocatalysis. Here we describe an approach to the engineering of the triplet excited states of aromatic chromophores, which involves incorporating pyrene into pyridinium-containing mechanically interlocked molecules (MIMs). The π-extended nature of the...
Article
The phenomenon of photon upconversion, in which a system absorbs two or more photons of lower energy and emits a photon of higher energy, has been used in numerous applications, including non-destructive bioimaging, deep-penetrating photodynamic therapy, catalysis, and photovoltaic devices. To date, photon upconversion has been observed typically i...

Collisional intermolecular interactions between excited states form short-lived dimers and complexes that lead to the emergence of excimer/exciplex emission of lower energy, a phenomenon which must be differentiated from the photoluminescence (PL) arising from the monomeric molecules. Although the utilization of noncovalent bonding interactions, le...

Neutral piano-stool complexes of the general formula [(η⁵-C5Me5)Rh(L-OR)] (R = Me, 1; R = Et, 2; R = Prⁱ, 3) have been prepared in alcohols (methanol, 1; ethanol, 2; isopropanol, 3) from the Schiff-base 5-methyl-4-{(pyridin-2-ylmethylene)amino}-4H-1,2,4-triazole-3-thiol (L-H) and the dinuclear precursor [(η⁵-C5Me5)RhCl2]2. Concomitant with the coor...
Article
We present a rapid and efficient method to generate a family of platinum supramolecular square complexes, including previously inaccessible targets, through the use of ball milling mechanochemistry. This one-pot, two-step process occurs in minutes and enables the synthesis of the squares [Pt4(en)4(N∩N)4][CF3SO3]8 (en= ethylenediamine, N∩N = 4,4’-bi...

The stereochemical properties of twelve dinuclear arene ruthenium complexes have been studied in solution.

Article
The electrochemical behavior of a dinuclear arene ruthenium complex containing a zwitterionic bridging ligand and of a hexacationic metalla-prism obtained from the assembly of three dinuclear zwitterion-bridged units and two tridentate panels has been investigated. The encapsulation of coronene in the hydrophobic cavity of the metalla-prism stabili...

Three new dinuclear arene ruthenium metalla-clips of the general formula [(p-cymene)2Ru2Cl2(μ-L)] have been prepared from [(p-cymene)2Ru2Cl2(μ-Cl)2] and H2L organic linkers (H2La = diethyl-1,2-diazenedicarboxylate, H2Lb = N,N′-bis(2-hydroxyethyl)oxamide, H2Lc = N,N′-bis{2-(2-hydroxyethoxy)ethyl}ethanediamide). The bis-chelating bridging-linkers pos...

In the structure of the title compound, C 8 H 6 Br 2 O 4 , the complete molecule is generated by the application of a centre of inversion. The molecule is planar (r.m.s. deviation for all non-H atoms but methyl C = 0.0358 Å), with only the methyl groups being deviated from the plane [by ±0.321 (4) Å]. In the crystal packing, Br...O(methoxy) halogen...

Six new pentamethylcyclopentadienyl Rh(III) and Ir(III) metalla-rectangles ([3](CF3SO3)4-[8](CF3SO3)4) have been prepared by a self-assembly strategy using the embelin-derived metalla-clips (η5-C5Me5)2M2(μ4-C6HRO4-κO)Cl2 (M = Rh, 1; M = Ir, 2; R = (CH2)10CH3) and the linear ditopic ligands, pyrazine, 4,4'-bipyridine and 1,2-bis (4-pyridyl)ethylene....

A series of arene ruthenium architectures have been prepared from coordination-driven self-assembly using dinuclear p-cymene ruthenium acceptors and π-donating tetratopic tetrapyridyl–tetrathiafulvalene donor ligands. The synthetic strategy, based on a geometric interaction approach, leads to four electroactive metalla-assemblies, 1–4 (one molecula...
