Abstract A novel anionic framework {[Me2NH2]0.5[In0.5L0.5]·xDMF}n (1) with two one-dimensional (1D) channels along the b axis of about 7.37 × 11.95 A and 6.58 × 7.24 A was solvothermally synthesized and characterized. The adsorption studies on organic dyes having different charges and sizes indicate that compound 1 exhibits selective adsorption and separation behavior for cationic dyes through an ion-exchange process due to the presence of an intrinsic anionic framework. Additionally, compound 1 can selectively separate methylene blue (MB+) from the cationic dyes mixture consisting of methylene blue (MB+) and rhodamine B (RhB+). Moreover, when implemented as chromatographic column stationary phases, compound 1 displays efficient and selective separation of MB+ from both anionic-cationic dyes mixture and only cationic dyes mixture.
