Naphthalenediimide cyclophane

A planar chiral naphthalenediimide cyclophane (39) and its derivatives were prepared for their tunable intramolecular FRET properties. The enantiomeric enrichment of cyclophane 39 was accomplished by chiral HPLC (on a Daicel IA column) and the CD spectra of enantiomeric 39 were reported (Fig. 9) [51]. 

Fig. 9 The CD spectra of chiral naphthalenediimide cyclophane 39 in dichloromethane. Solid lines experimental spectra for enantiomerically enriched samples (concentration 8.1 and 7.0 pM for first and second peaks, respectively). Dotted lines spectra of pure enantiomers corrected for the enantiomeric purities of the sample obtained by chiral HPLC. Reprinted with permission from [50].
