Fig. 6. Photophysical and chiroptical properties. (A) Absorption (solid line) and fluorescence (broken line) spectra of [(Sp,Sp)-(M,M,M,M)-1a (red) and (Sp,Sp,Rp)-(M,M,M,M,P,P)-1b (blue) in CH₂Cl₂ at 25 °C. ECD (B) and CPL (C) spectra of 1a (solid line) [(Sp,Sp)-(M,M,M,M)-1a: red, (Rp,Rp)-(P,P,P,P)-1a: blue] and 1b (broken line) [(Sp,Sp,Rp)-(M,M,M,M,P,P)-1b: red, (Rp,Rp,Sp)-(P,P,P,P,M,M)-1b: blue] in CH₂Cl₂ at 25 °C. (D) Calculating the energy diagrams of (M,M)-8, (Sp,Sp)-(M,M,M,M)-Me₄-1a, (Sp,Sp,Rp)-(M,M,M,M,P,P)-Me₆-1b, and [8]CPP. (E) Calculating the transition dipole moments of (M,M)-8, (Sp,Sp)-(M,M,M,M)-Me₄-1a, (Sp,Sp,Rp)-(M,M,M,M,P,P)-Me₆-1b, and (R,R,R,R)-9.
