Self-assembly processes of 2D Au(I)-S(CH)COOH lamellae.

Solving the assembled structure of Au(I)-thiolate linear coordination polymers has been a challenging task as they generally lack good crystallinity. This has prevented the elucidation of their assembly processes at the molecular level. In this paper, selected area electron diffraction (SAED) patterns of two-dimensional (2D) Au(I)-S(CH)COOH (Au(I)-MPA) lamellae are obtained by applying cryogenic transmission electron microscopy.

Effect of the 1D/2D dimensionality in copper and silver thiolate coordination polymers on their photophysical properties.

A series of four new copper and silver-thiolate, [M(-SPhCOR)] (M = Cu, Ag and R = H, Me), coordination polymers is reported. The study shows that the hydrogen bonding between the carboxylic acids directs the formation of a 2D structure associated with poor photoemission, while the steric hindrance of the ester groups allows the assembly of a 1D network coupled with bright luminescence.

Visualizing the spatial organization of monocytes, interstitial macrophages, and tissue-specific macrophages in situ.

Tissue-resident mononuclear phagocytes (MPs) are an abundant cell population whose localization in situ reflects their identity. To enable assessment of their heterogeneity, we developed the red/green/blue (RGB)-Mac mouse based upon combinations of Cx3cr1 and Csf1r reporter transgenes, providing a complete visualization of their spatial organization in situ. 3D-multi-photon imaging for spatial mapping and spectral cytometry employing the three markers in combination distinguished tissue-associated monocytes, tissue-specific macrophages, and three subsets of connective-tissue-associated MPs, including CCR2 monocyte-derived cell, CX3CR1, and FOLR2 interstitial subsets, associated with distinct sub-anatomic territories.

Site-directed cation ordering in chabazite-type AlGaPO-34 frameworks revealed by NMR crystallography.

We report the first synthesis of the mixed-metal chabazite-type AlGaPO-34(mim) solid solution, containing 1-methylimidazolium, mim, as structure directing agent (SDA), from the parent mixed-metal oxide solid solution, γ-(AlGa)O. This hitherto unreported family of materials exhibits complex disorder, arising from the possible distributions of cations over available sites, the orientation of the SDA and the presence of variable amounts of water, which provides a prototype for understanding structural subtleties in nanoporous materials. In the as-made forms of the phosphate frameworks, there are three crystallographically distinct metal sites: two tetrahedral MO and one octahedral MOF (M = Al, Ga).
