(a) UV-visible absorption spectrum and emission spectrum of CB-CYH in pure THF (10^-4 M). (b) Electron density distributions of LUMO and HOMO molecular orbitals of CB-CYH calculated by the B3LYP/6-31Gd program. (HOMO: the highest occupied molecular orbital energy; LUMO: the lowest unoccupied molecular orbital energy).
