In this study, we constructed a novel solid state supramolecular system-the molecular cage ZnOTCPP, based on an inorganic/organic hybrid nanostructure, through the assembly of 5,10,15,20-tetra(3-carboxyphenyl)porphyrin (TCPP) onto the surfaces of ZnO nanorod (NR) arrays. The ZnOTCPP molecular cage exhibited highly selective recognition of 5,10,15,20-tetraphenylporphyrin (TPP) by optical and pho...

The synthesis and structure of a novel decanuclear copper(II) cage is reported. The assembly of the cage is facilitated by the cumulative coordinative interaction of tert-butyl phosphonate, 2-pyridylpyrazole and hydroxide ligands with copper(II) ions. Magnetic studies of this decanuclear copper(II) cage indicate complex antiferromagnetic behaviour.

We synthesize a series of imine cage molecules where increasing the chain length of the alkanediamine precursor results in an odd-even alternation between [2 + 3] and [4 + 6] cage macrocycles. A computational procedure is developed to predict the thermodynamically preferred product and the lowest energy conformer, hence rationalizing the observed alternation and the 3D cage structures, based on...

Security has become the corner stone of research in wireless sensor networks (WSNs). Due to the unique operational environment of WSNs, where the communication medium is open to eavesdroppers, the threats manifest in new forms necessitating the safeguarding of communication. Consequently, key management protocols have become paramount in mitigating the damage caused. Numerous group-key protocol...

BACKGROUND Avian hepatitis E virus (HEV) infection is common in chicken flocks in China, as currently no measures exist to prevent the spread of the disease. In this study, we analyzed the effect of caged versus cage-free housing arrangements on avian HEV transmission. First, 127 serum and 110 clinical fecal samples were collected from 4 chicken flocks including the two arrangements in Shaanxi ...

A metallosupramolecular [Pd2L4](4+) cage can be cleanly converted into a [Pd2L2Cl4] metallo-macrocycle upon addition of chloride ions. The process is reversible, treatment of the [Pd2L2Cl4] macrocycle with silver(I) ions regenerates the [Pd2L4](4+) cage. Additionally, it is shown that guest molecules could be released on chloride triggered cage dis-assembly and taken up anew on re-assembly.

Under UV-light irradiation, the anti-Markovnikov hydration of internal arylalkynes proceeds in the cavity of an electron-deficient coordination cage to give benzyl ketones; the reaction is triggered by cage-mediated, photo-induced electron transfer from the alkynes to the cage.

the interaction of a nitrosyl hydride (hno) molecule with b12n12 nanocage was explored by means of density functional calculations. it was found that hno prefers to be adsorbing on a boron atom of the cage with adsorption energy of -0.65 ev. this adsorption process significantly shifts the homo-lumo gap (eg) of the cage to lower energies, thereby reducing eg of the cage from 6.84 to 2.45 ev. ti...
