A Switchable Open/closed Polyaromatic Macrocycle that Shows Reversible Binding of Long Hydrophilic Molecules

supporting information, p. 11360 - 11364 (2017/09/11)

In spite of wide-ranging previous studies on synthetic macrocycles, the installation of open–close functions into the frameworks remains a challenge. We present a new polyaromatic macrocycle capable of switching between open and closed forms in response to external stimuli, namely, base and acid. The macrocycle, which is prepared in three steps, has a well-defined hydrophobic cavity with a length of around 1 nm, surrounded by four pH-responsive acridinium panels. The open and closed structures were confirmed by single-crystal X-ray analysis. The cylindrical cavity can bind long hydrophilic molecules up to 2.7 nm in length in neutral water and then release the bound guests through a reversible open-to-closed structural change upon simple addition of base.

Amphiphile cyclodextrins, preparation and use thereof for solubilizing organized systems and incorporating hydrophobic molecules

-

, (2008/06/13)

The invention provides cyclodextrin derivatives that may be used to transport hydrophobic molecules for pharmaceutical or cosmetic applications, by forming organised systems in an aqueous medium, alone or with phospholipids. The cyclodextrin derivatives of the present invention have the formula: in which, R¹ represents a steroid, R² represents an alkyl or aryl group, substituted if applicable, R³ represents H or R², all the R⁴ represent OR², or one of the R⁴ represents —NHCO(CH₂)_mCONHR¹, m is an integer ranging from 1 to 8, and n is equal to 5, 6 or 7.
