Figure 3. — (a) The chemical structure of the AIE-active β-diketonate boron complex. (b) Photoelectronic spectra of DKMeO in various solvents. (c) Photographic images of DKMeO in hexane, toluene, tetrahydrofuran (THF) and acetonitrile under UV irradiation. (d) Photoluminescence spectra of blue suspension (dotted line) and time-dependent spectra of green suspension (solid lines) in 5 × 10^–5 M CH₃CN/water mixture at 85% and 95% fraction of water (f_w), respectively. (e) A plot of relative luminescent intensity versus f_w. I₀ represents emission intensity in pure 5 × 10^–5 M CH₃CN solution. Reprinted with permission from ref [23].
