Preferred Label : cyclophanes;
IUPAC definition : The term originally applied to compounds having two i p /i -phenylene groups held
face to face by –[CH sub 2 /sub ] sub i n /i /sub – bridges. It now designates compounds
having (i) mancude-ring systems, or assemblies of mancude-ring systems, and (ii) atoms
and/or saturated or unsaturated chains as alternate components of a large ring. E.g.
[2.2](1,4)(1,4)cyclophane [or 1(1,4),4(1,4)-dibenzenacyclohexaphane]. Many chemists
include in this class any bridged aromatic system, irrespective of the attachment
positions of the bridge.;
