Abstract

Water-soluble homodimeric capsules resulting from the electrostatic and hydrophobic interactions between a tetracationic calixarene receptor and gemini guests having the negatively charged ends separated by a (–CH2–) n (n= 2–6) spacer are reported. The formation of the supramolecular capsules occurs through concerted hydrophobic and electrostatic interactions between the charged and aromatic groups of the guests and the ...
