2022年8月15日 · Plasma ammonia synthesis explored over Porous Organic Cage (CC3). CC3 displayed high ammonia yields compared to other microporous crystals. CC3 crystals were translated into a Prototypical Plasma-Membrane Reactor. CC3-membranes dual functionality (adsorber + separator) avoids NH 3 decomposition.

2020年2月1日 · We demonstrate a Humidity Modulated Solvent Evaporation (HMSE) approach to promote the nucleation and growth of CC3 crystals. This approach relies on the gradual evaporation of dichloromethane (solvent) from a diluted concentration of CC3 precursors deposited on aluminum foil.

Figure 1 shows the PXRD patterns of CC3 crystals synthesized via microwave as a function of synthesis time (experimental details on the microwave synthesis conditions are given in the Supporting Information). All XRD patterns correspond to the common topology of CC3α crystals.

2024年3月1日 · The broad diffraction peaks appeared in the XRD pattern of PVAm self-standing film, indicating its amorphous nature. In contrast, the XRD pattern of CC3 (28.6 %)/PVAm self-standing film displayed all characteristic peaks of CC3 crystals, suggesting that the crystal structure of CC3 was not damaged during mixing.

2024年5月9日 · Here, the authors report the preparation of homochiral porous organic cage (Covalent cage 3 (CC3)- R)-based enantioselective thin-film-composite membranes using polyamide (PA) as the matrix, where fully organic and solvent-processable cage crystals have good compatibility with the polymer scaffold.

2016年1月22日 · In the solid state, ASPOC shows a poorly ordered morphology, while CC3, CC13, and FT-RCC3 have a regular octahedral crystal morphology (Figure S2, Supporting Information). X-ray diffraction (XRD) patterns of the cage solids confirmed their crystalline structure (Figure S3, Supporting Information).

Here, we use a prototypical POC, CC3, to explore the potential to tune cage properties via post-synthetic dynamic covalent chemistry. Ethylenediamine, the linker used in another POC CC1, was partially substituted into the CC3 cage structure to varying degrees based …

Herein we followed the structural evolution of a prototypical type of porous organic cage, CC3, as a function of synthesis time. Three distinctive crystal formation stages were identified: at short synthesis times, a rapid crystal growth stage in which amorphous agglomerates transformed into larger irregular particles was observed.

ci-nal diamines (vertex groups) has a profound effect on how the cages crystallise as porous solids. For example, CC3, which has cyclohexyl vertex groups, typically packs window-to-window (Fig. 1a) and crystall.

In this paper, the hydrothermal method was utilized for the facile synthesis of copper chromite nanoparticles in the absence (abbreviated as CC1) and presence of citric acid (abbreviated as CC2)...
