a Changes in fluorescence spectrum of 2.0 μM S-C[4]B upon addition of S-1-NA (up to 80 μM). b Changes in fluorescence spectrum of 2.0 μM S-C[4]B upon addition of R-1-NA (up to 74 μM). c The fitting curve plot of S-C[4]B upon addition of S-1-NA and R-1-NA for emission at λ = 400 nm, according to the nonlinear curve fitting with 1:2 host-guest binding model.
