Mechanochromism of Dinuclear Aluminum-based Triple-stranded Helicates through Crystalline-to-Amorphous Phase Transition

Key Points

• The research aims to investigate how mechanical grinding affects the color and structure of aluminum-based helicates.
• Examined dinuclear aluminum triple-stranded helicates with various halogenated substituents.
• Applied mechanical grinding to induce color changes.
• Utilized powder x-ray diffraction to confirm crystalline-to-amorphous phase transitions.
• Distinct color changes were observed after mechanical grinding.
• Phase transitions between crystalline and amorphous forms were confirmed through x-ray diffraction.
