Stable dye-encapsulated indium–organic framework as dual-emitting sensor for the detection of Hg 2+ /Cr 2 O 7 2− and a wide range of nitro-compounds

A water-stable porous anionic metal–organic framework (MOF), (CH 3 ) 2 NH 2 In(TNB) 4/3 ·(2DMF)(3H 2 O) ( 1 , H 3 TNB = 4,4′,4′′-nitrilotribenzoicacid), was synthesized.
