Abstract:
Two water-stable silver(i) cation metal organic frameworks (MOFs), namely 2D MOF {[Ag(L)₂]BF₄}ₙ (1) and 3D MOF {[Ag₃(L)₃]·(H₂O)·(CF₃SO₃)₃}ₙ (2) (L = 1-(4-aminobenzyl)-1,2,4-triazole), have been prepared. 1 is the first example of a 2D MOF-based sensor for real-time discrimination of l- and d-cysteine from other amino acids through the quenching effect. Through deliberately tuning the nanoparticles of 2 under ultrasound conditions, these nanoparticles are, for the first time, successfully applied as an excellent DNA detecting platform.
