Gravimetric/visual iodine uptake from vapour and cyclohexane solution; ethanol release monitored visually and by UV-vis

UV-visible and optical absorption spectroscopy

iodine-loaded compound 1' subset nI2 · Pellet

Solution uptake used 3 mL 0.01 M I2 in cyclohexane and 50 mg activated 1' for 1 h; release used 1 mg 1' subset nI2 in 2 mL dry ethanol at room temperature.

Atmosphere: closed vial for solution uptake; dry ethanol for release
Geometry: crystalline powder
Context: guest-loaded framework
