Summary
Researchers developed a novel metal-organic framework (MOF) using flexible aggregation-induced emission luminogens (AIEgens). This AIEgen-based MOF exhibits tunable luminescence switched by guest molecules, offering insights into guest-triggered emission mechanisms.
Area of Science:
- Materials Science
- Supramolecular Chemistry
- Luminescence
Background:
- Aggregation-induced emission luminogens (AIEgens) are crucial for developing luminescent metal-organic frameworks (MOFs).
- Achieving MOFs with adjustable emission properties using AIEgens is challenging due to their rigid conformations in crystalline states.
Purpose of the Study:
- To design and synthesize a novel 3D silver chalcogenolate cluster MOF incorporating flexible AIEgens.
- To investigate the influence of guest molecules on the conformational flexibility and luminescent properties of the AIEgen-based MOF.
- To establish a visualized prototype for understanding guest-triggered aggregation-induced emission in MOFs.
Main Methods:
- Design and synthesis of a dual-node 3D silver chalcogenolate cluster MOF (1).
- Characterization of the MOF structure and luminescent properties.
- Investigation of guest molecule adsorption/desorption effects on ligand conformation and luminescence.
Main Results:
- The synthesized MOF (1) features AIE ligands with flexible and rotatable conformations.
- The MOF exhibits intense luminescence that is switchable upon absorption/desorption of guest molecules.
- The switching rate of luminescence is tunable by employing different guest molecules.
Conclusions:
- The developed MOF demonstrates a strategy for creating highly luminescent MOFs with adjustable emission properties.
- The study provides a unique platform for visualizing and understanding guest-triggered aggregation-induced emission mechanisms in MOFs.
- This work opens avenues for designing responsive luminescent materials for sensing and optoelectronic applications.

24.5K
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

02:39Emission Spectra
76.2K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

20.6K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

02:58Properties of Transition Metals
29.8K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
