two novel two-dimensional(2d)supramolecular organic frameworks were fabricated in water based on the encapsulation-enhanced donor-acceptor interaction between the methyl viologen(mv)units,methoxy naphthyl(mn)units,and cb[8].the tetraphenylethylene(tpe)derivatives 1 with four mv units were employed as rigid building blocks and the two mn units modified oligoethylene glycol derivatives 2 and 3 served as flexible edges,respectively.the obtained two sofs have obvious sheet-like structures and exhibit fluorescence emission at 350-500 nm.in addition,these two sofs were employed for the luminescent detection of cr(vi)and mn(vii)in aqueous solutions,and the detection limits of cro_(4)^(2-),cr_(2)_(o)7%^(2-),and mno_(4)were calculated in a very low concentration range,indicating that these two sofs can serve as a potential sensor for cr(vi)and mn(vii)detection in water.this work constructs two sofs in an aqueous solution through a facile method and further enriches the applications of sofs.
