Nano-complex formation of cyclodextrin and azobenzene using supercritical carbon dioxide

Peracetylated β-cyclodextrin as solubilizer of arylphosphines in supercritical carbon dioxide

“…However, it must be emphasized that the formation of the inclusion complexes was achieved by feeding a stream of CO 2 containing the guest compound through a suitable vessel packed with a CD bed or by exposing a physical mixture of the guest compound and ␤-CD to the supercritical fluid. In all cases, the CD was insoluble in the scCO 2 and no procedure requires the solubilization of the inclusion complex to recover it [25][26][27][28][29]. In this context, the results reported here constitute the first example of inclusion complex soluble in scCO 2 medium and indicate that host-guest interactions in scCO 2 can occur.…”

Binary Crystallized Supramolecular Aerogels Derived from Host–Guest Inclusion Complexes

“…On the other hand, the free R-CDs and unthreaded PEG could be washed out by extraction with SC CO 2 , while the PPR can be reserved in it. 44,45 As shown in Table 1, the densities of the SMAs are lower than 100 mg/cm 3 , and high porosities from 93.8 to 96.0% have been achieved. It should be pointed out that the densities of the SMAs are smaller than the theoretic values, and it might be attributed to the weight loss of free CD and PEG during solvent extraction of SC CO 2 , though a little volume shrinkage was happened after drying.…”

“…Though solvent-exchange (which is a requisite for the supercritical (SC) CO 2 liquid drying) with DMF, THF, or ethanol may dissolve or disrupt the SMHGs, we luckily found that the SMHGs were stable in acetone (see Figure S1 in the Supporting Information), and the corresponding acetone-gel can be dried under SC CO 2 . On the other hand, the free α-CDs and unthreaded PEG could be washed out by extraction with SC CO 2 , while the PPR can be reserved in it. , As shown in Table , the densities of the SMAs are lower than 100 mg/cm 3 , and high porosities from 93.8 to 96.0% have been achieved.
