Relating solvatochromism and solvatomorphism in organic dyes using high pressure.

ABSTRACT

By using complementary experimental methods including in situ high-pressure single-crystal X-ray diffraction and UV-Vis spectroscopy, the intricate connection between solvatochromism and solvatomorphism has been elucidated in a recent publication [Sobczak & Katrusiak (2024). IUCrJ, 11, 528-537]. The connection was demonstrated for an important pigment - Reichardt's dye - with potential applications in nonlinear optoelectronics and molecular pressure sensor development.
