Fig. 1. Photophysical properties of 9. (Left) Luminescence photographs taken under UV light (365 nm) and fluorescence spectra with different water volume fractions (vH2O/vTHF%) of 9 (1.0 × 10−5 M, λex = 323 nm) under ambient conditions; (right) fluorescence spectra of 9 observed in different solvents (1.0 × 10−5 M, λex = 323 nm) under ambient conditions.
