a Circular dichroism (CD) spectra (10 μM, CHCl3, RT) of Δ- and Λ-[2a]Cl in the presence of resorcin[4]arene 1a (0, 30, 60, 120 μM). b Normalized circularly polarized luminescence (CPL) spectra (50 μM, CHCl3, RT) of enantiomerically pure Ir complex [2a]Cl (50 μM) with resorcin[4]arene monomer 1a (0, 300, 600 μM), which was obtained from division of the 2ΔI curve by the maximum of the emission intensity. All samples solutions containing [2a]Cl and 1a were heated at 50 °C for 1 min before the measurements.
