Flat Macrocycles Based on p ‐Quaterphenyl Units [1.1](3,3′″)‐ p ‐Quaterphenylophanes 1 – 3 are synthesized via 6 – 12 starting with biphenyl derivative 5 . The properties of 1 – 3 (UV, NMR) and their charge‐transfer complexation are compared to p ‐quaterphenyl. 1 – 3 are high‐melting, colorless solids, which are sparingly soluble in common organic solvents. They contain two “isolated” p ‐quaterphenyl units. Similar to p ‐quaterphenyl, 2, 2a and 3 form greenish‐blue chargetransfer complexes with tetracyanoethene (TCNE) in CH 2 Cl 2 .
