Molecular and Ionic Solids

20.2K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Vapor Pressure

40.9K
When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...

Definition and Measurement of Pressure: Atmospheric Pressure, Barometer, and Manometer

43.5K
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any surface of an appreciable area experiences a large number of collisions in a short time, which can result in high pressure.

Area of Science:

  • Coordination Chemistry
  • Materials Science
  • Spectroscopy

Background:

  • Chromium(III) complexes are known for their luminescent properties.
  • Optical pressure sensing typically relies on materials like ruby (Al₂O₃:Cr³⁺).
  • Understanding pressure effects on luminescent materials is crucial for developing new sensors.

Purpose of the Study:

  • To investigate the pressure-induced spectral shifts of novel chromium(III) complexes.
  • To evaluate their potential as optical pressure sensors compared to established standards.
  • To explore their application in different states, including solutions.

Main Methods:

  • Synthesis and characterization of chromium(III) complexes [Cr(ddpd)₂]³⁺ and [Cr(H₂tpda)₂]³⁺.
  • High-pressure spectroscopic measurements to determine emission band shifts.
  • Quantum yield measurements to assess luminescence efficiency.

Main Results:

  • Observed significant pressure-induced red shifts (-15 cm⁻¹ kbar⁻¹) in spin-flip emission bands.
  • These shifts are approximately 20 times greater than those observed in ruby.
  • [Cr(ddpd)₂]³⁺ demonstrates high quantum yield, enabling sensing in solution.

Conclusions:

  • Novel chromium(III) complexes act as highly sensitive molecular rubies for optical pressure sensing.
  • Their superior performance surpasses traditional ruby sensors.
  • These complexes offer new avenues for molecule-based pressure sensing in diverse environments.
