Figure 6From: pH-controlled release of auxin plant hormones from cucurbit[7]uril macrocyclePlot of absorbance changes at 525 nm as a function of [CB[7]]/[CB[7] + [IAA]. Line shows best fit of the experimental data to the 1:1 binding model. Aobs, absorbance observed; ACB[7], absorbance CB[7]; AIAA, absorbance IAA.Back to article page
