Summary
This study introduces a novel coordination network with dual-stimuli-responsive luminescence. The material smoothly shifts emission color across the visible spectrum under thermal or pressure changes, reversibly.
Area of Science:
- Materials Science
- Supramolecular Chemistry
- Luminescence
Background:
- Coordination networks offer tunable properties through structural design.
- Stimuli-responsive materials are crucial for advanced sensors and actuators.
- Luminescence modulation in solids remains a key research area.
Purpose of the Study:
- To develop a new coordination network exhibiting dual-stimuli-responsive luminescence.
- To investigate the relationship between structural deformation and luminescence changes.
- To demonstrate reversible color tuning across the visible spectrum.
Main Methods:
- Synthesis of a novel coordination network incorporating organic fluorophores.
- Application of thermal and pressure stimuli to induce structural deformation.
- Spectroscopic analysis (luminescence spectroscopy) to monitor emission shifts.
- Structural characterization to correlate deformation with luminescence.
Main Results:
- The coordination network exhibits smooth, reversible deformation under thermal and pressure stimuli.
- Organic fluorophores adapt conformation and arrangement upon structural changes.
- A dual-stimuli-responsive luminescence shift from cyan to green (heating) and red (compression) was observed.
- Linear dependence of emission maximum and intensity on stimulus was confirmed.
Conclusions:
- A novel coordination network with tunable, reversible luminescence properties has been synthesized.
- The material demonstrates significant potential for applications in responsive displays and sensors.
- The observed luminescence shift across the visible spectrum highlights the material's unique photoresponsive capabilities.

02:57Coordination Number and Geometry
19.0K
For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

26.7K
In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

02:33Lattice Centering and Coordination Number
11.5K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

14.1K
The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

00:54What is Behavior?
10.3K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
