文摘

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.
