Encapsulation of dyes in metal–organic frameworks and their tunable nonlinear optical properties†
Two series of cationic dyes, named DM-n and DP-n, were encapsulated in three anionic isostructural MOFs with a 1D channel. Ordered arrangement of the dyes in the channel was investigated by using the microscope polarized absorption spectra of different dye and MOF composites. Furthermore, the tunable second order nonlinear optical properties of these MOF⊃dye materials were observed.
