Fig. 5.20 Photographs of the crystal 3O obtained by recrystallization from CH 2 Cl 2 with hexane.
There is no emission color change upon liquid MeOH addition. The photographs were taken under
UV light (365 nm)
Fig. 5.21 Photographs of mechanochromism using semi-crystalline powder 3G/MeOH. The grinding was performed by ball-milling for 20 min. The powder of 3O grinding was obtained by grinding the
powder sample of 3G/MeOH. Upon adding MeOH solvent, 3O grinding changed into yellow-emitting
powder 3O . The photographs were taken under UV light (365 nm)
