Fig. 5: Photoarrangement of Z-CDPM.
From: A chameleon AIEgen exhibiting six distinct yet tunable thermal and photoswitchable states
a Photoarrangement of Z/E-CDPM and single crystal structures of HBNPMM. b Photoluminescence (PL) spectra of HBNPMM (10 μM) in THF/water mixtures. Inset: plots of I/I0 value versus water fractions (fw) of THF/water mixtures of HBNPMM, where I0 = PL intensity in pure THF solution. λex/em = 365/460 nm. c PL spectral change of Z-CDPM before and after UV irradiation at 365 nm for different times (1, 2, 3, 5, 7, 10, and 30 s). λex = 365 nm d 1H NMR spectra of the photoarrangement of Z/E-CDPM in C2D2Cl4 (500 MHz). Z-CDPM (red line) and E-CDPM (orange line) were irradiated by 365 nm UV irradiation from a 365 hand-hold UV lamp for 30 min, and the black line was HBNPMM. e Energy profile for the photoarrangement of Z-CDPM calculated at the M06-2X/6-31 G(d,p) level with solvent correction. TS transition state, INT intermediate.
