New single-and mixed-linker Cr-MIL-101 derivatives bearing different functional groups,-F,- Cl,-Br,-NH2,-NO2,-H,-SO3H,-CH3, and-COOH, have been synthesized. High-throughput methods were employed to investigate the influence of the metal source (CrO3, CrCl3, and Cr (NO3) 3· 9H2O), the linker functionalization, and the use of mixtures of linkers on product formation. Postsynthetic modification was successfully carried out to selectively reduce the ...
