Nonlinear Optical Rod Indium-Imidazoledicarboxylate Framework as Room-Temperature Gas Sensor for Butanol Isomers

The mimic of classic [Co­(en)3]-like (en = ethylenediamine) structure generates a 3D chiral indium-imidazoledicarboxylate framework (SNNU-50) exhibiting significant SHG effects. 1D rod building units in SNNU-50 lead to a band gap value comparable to that of In2O3. Different from the high temperature...

Description
Summary:The mimic of classic [Co­(en)3]-like (en = ethylenediamine) structure generates a 3D chiral indium-imidazoledicarboxylate framework (SNNU-50) exhibiting significant SHG effects. 1D rod building units in SNNU-50 lead to a band gap value comparable to that of In2O3. Different from the high temperature metal oxide semiconducting sensor, MOF sensor prepared by the SNNU-50 sample demonstrates remarkable selectivity and low detection limit to four butanol isomers at room temperature. Notably, SNNU-50 represents the first MOF sensor showing the ability for structural isomer identification, which may open up a new promising application for porous metal–organic frameworks.
