a UV–Vis and CD spectra (chloroform, 25 °C) of pR-1, pS-1, and mixtures of 4 with pR-1 or pS-1. The concentrations of 1 and 4 were 0.05 and 0.1 mM, respectively. b Simulated (Sim.) and experimental (Exp.) high-resolution ESI-MS spectra of a mixture of 4 with pS-1. c, d Partial 1H NMR spectra (600 MHz, CDCl3, 25 °C) for as-prepared mixtures of c rac-1 and 4, and d pS-1 and 4. The DOSY NMR spectrum (500 MHz, CDCl3, 25 °C) of the as-prepared mixture of pS-1 and 4 is also shown in d. For all 1H NMR spectra, the concentrations of 1 and 4 were 0.5 and 1.0 mM, respectively. e Molecular structures of the three trimers in the mixture of pS-1 and 4.
