14. Liquid-phase adsorption using OBPc was typically performed as follows: OBPc (2 mg) was dissolved in 100 mL of hexane. The solution was cooled to 0°C and x (= 40-90) mg of 8Az2-MSU-H powder was dispersed in the solution. After stirring for 12 h, 5 mL of suspension was pipetted from the well-dispersed solution, followed by an immediate and rapid filtration (within five minutes) to isolate an unadsorbed OBPc solution. The concentration of the unadsorbed OBPc solution was determined using UV-vis spectrum. The remaining suspension was exposed to the UV light for 1 h. The solution was stirred for 1 h in the dark and the concentration was similarly determined using another 5-mL suspension. Thus, vis and UV light irradiation was alternately repeated.
