✦ Synopsis

The stability constants I( of the 1:l host to guest complexes formed between eight phenols and the cyclis tetramer, cyclotetr chromotropylene, 't in an aqueous solution at pD 7.0 at 25 C were determined b H nmr spectroscopy. They vary from -0 (p-sodium sulfonatophenol) to 400 M _y (pnitrophenol).
