The MOF matrices for pigments with encapsulated dmit

MOF-5 and ZIF-8 were used for the first time as matrices for pigments containing entrapped dmit. The chromophore was introduced either by impregnation or by its synthesis from CS2 inside the matrices. Pigments with ZIF-8 resisted washing and maintained the structure, while these with MOF-5 underwent structure altering or amorphization.

► The ZIF-8, MOF-5 appeared efficient matrices for stable dmit pigments.
► Entrapping of dmit can be attained either by impregnation or by synthesis of dye inside MOF voids.
► Probably dmit molecules form bulky complexes with structural Zn cations.
► ZIF-8 structure is not affected, while MOF-5 undergoes some transformation on pigment synthesis.
