Triphenylamine-based rhombimine macrocycles with solution interconvertable conformation

Three imine macrocycles having rhomboidal shape were synthesized in good yields by [2+2] cyclocondensation reaction between equimolar quantities of (R,R)-1,2-diaminocyclohexane and 4,4′-bisformyl triphenylamine derivatives. The macrocycles structure was a

Synthesis of a triphenylamine-based macrocycle with rhombimine shape

A Schiff base macrocycle having rhomboidal shape was synthesized through [2+2] cyclocondensation reaction between 4,4'-diformyl triphenylamine with (R,R)-1,2-diaminocyclohexane. The macrocyle structure was unambiguously proved by electrospray ionization mass spectrometry (ESI-MS), FTIR and 1H-NMR spectroscopy. The change of macrocycle's conformation in solution was observed by 1H-NMR and UV spectroscopy. Reduction of rhombimine led to a rhombamine macrocycle.
