The interlocking of ring and axle molecular components in rotaxanes provides a way to combine chromophoric, electron-donor and electron-acceptor moieties in the same molecular entity, in order to reproduce the features of photosynthetic reaction centers.

A snowflake-like supramolecular clockwise-helical assembly was fabricated via the host-guest interaction of trans-azobenzene-bridged bis(dibenzo-24-crown-8) (trans-1) and a cholesterol derivative, while a snowflake-like supramolecular non-helical assembly
A new class of flavonoids bearing macrocyclic polyethers by stereoselective photochemical cycloaddition reaction
Ishikawa, Hiroki,Uemura, Naohiro,Taira, Ryo,Sano, Kento,Yoshida, Yasushi,Mino, Takashi,Kasashima, Yoshio,Sakamoto, Masami

A new class of flavonoids bearing cyclic polyethers involving a phenyl ring was conveniently provided by the intramolecular photochemical dimerization of 2-chromonecarboxylic esters. Irradiation of 2-chromonecarboxylate with a polyether tethered at both ends promoted intramolecular [2 + 2] cyclobutane formation leading to 14- to 27-membered cyclic polyethers. The efficiency depended on the substituted position of the phenyl ring, with ortho- and meta-substituted derivatives giving cycloadducts in good chemical yields and quantum efficiencies, whereas the para-derivatives were inert toward photolysis. X-ray crystallographic analysis revealed that the stereochemistry of the macrocyclic cycloadducts exhibited C2-symmetry.
