Cage‐to‐Cage Cascade Transformations
Chemistry – A European Journal, 2016AbstractA series of Pd2L4‐type binuclear self‐assembled coordination cages (1–4), where L stands for a nonchelating bidentate ligand, were prepared. The strategies adopted for the synthesis of the cages were: combination of PdII with 1) a selected ligand or 2) subcomponents of the ligand.

Various cages are constructed by using three types of caps: f-cap (derived from spherical fullerenes by deleting zones of various size), kf-cap (obtainable by cutting off the polar ring, of size k), and t-cap ("tubercule"-cap). Building ways are presented, some of them being possible isomerization routes in the real chemistry of fullerenes.

Frontier Orbitals of Trivalent Cages: (3,6) Cages and (4,6) Cages
The Journal of Physical Chemistry A, 2005A qualitative molecular-orbital treatment and group-theoretical analysis reveals the nature of the frontier orbitals of (3,6) and (4,6) polyhedral cages, consisting of a hexagonal network with triangular and square defects, respectively. Leapfrog (3,6) cages have two nonbonding filled orbitals.

A photoactivatable caged cyanide, 1-(2-nitrophenyl)ethyl (NPE) cyanide, was synthesized, which upon irradiation in the near UV releases cyanide. It is demonstrated that the compound can be used to induce formation of the Fe(III)-CN(-) complex in the heme protein nitrophorin 4 from Rhodnius prolixus.

AbstractWe discuss the problem of finding smallest graphs of given girth g and valency v ((v, g)‐cages). All known (v, g)‐cages are given. Different variations of the cage problem are also discussed.

Pacific Historical Review, 2019
Border fences have a long history in the United States, and that history is deeply entangled with the rise of the carceral state. As fences along the U.S.-Mexico border grew over the course of the twentieth century, they increasingly restricted the mobility of migrants both as they crossed the U.S.-Mexico divide and once they were within U.S. territory.

We report the results of density functional theory for 39 clusters AxBy (x + y = 10 or 12) where A and B are metals from group 1, 2, 11, 12, 13, or 14 of the periodic table. The chemical compositions were chosen to satisfy an electronic shell closing criterion.

The authors show that any \((k,g)\)-cage \((k\)-regular graph with girth \(g\) and smallest possible number of vertices) is 2-connected. They conjecture that any simple \((k,g)\)-cage is \(k\)-connected and prove the conjecture for \(k=3\).

Homochiral Dodecanuclear Lanthanide “Cage in Cage” for Enantioselective Separation
Journal of the American Chemical Society, 2021It is extremely difficult to anticipate the structure and the stereochemistry of a complex, particularly when the ligand is flexible and the metal node adopts diverse coordination numbers. When trivalent lanthanides (LnIII) and enantiopure amino acid ligands are utilized as building blocks, self-assembly sometimes yields rare chiral polynuclear ...
