From: Multiple yet switchable hydrogen-bonded organic frameworks with white-light emission
a The photographs of different crystals of 4CN under daylight (first row) and UV light (second row). b Normalized fluorescent emission spectra of different crystals. c The corresponding simulated PXRD patterns of different crystals, that is, 4CN(ET2) and 4CN(MT) in group 1 (G1), 4CN(ET1) in group 2 (G2), 4CN(Non1) and 4CN(Non2) in group 3 (G3) or 4CN(THF), 4CN(DCM) and 4CN(TCM) in group 4 (G4).
