Fig. 2. PL properties of AIEgens in solution. (a) Normalised absorption (black lines, 20 μM in THF) and emission (red lines, 20 μM in 10 : 90 THF : H2O volume mixture) spectra of DMTPS (solid lines) and DMTPS-Sil (dashed lines), with λex (for emission spectra) = 370 and 390 nm, respectively. Emission spectra of (b) DMTPS (λex = 370 nm) and (c) DMTPS-Sil (λex = 390 nm) measured in pure THF (black) and 10 : 90 (v/v) THF–H2O mixture (red). N.B.: The emission intensity of DMTPS in THF (b) is negligible and lies at the baseline.
