I2-induced SC–SC transformation within two-dimensional Zn(ii)-triazole framework: an ideal detector of cyano-containing molecules†
Abstract
A novel interpenetrated 2D + 2D → 2D architechture {[Zn(BTPS)(TPA)]·1.5DMF·H2O}n (1) has been constructed under solvothermal conditions. Interestingly, I2-induced single-crystal-to-single-crystal transformation to {[Zn(BTPS)(I)(TPA)1.5]·1.5H2O}n (1′) showed a 2D + 1D → 2D array. Luminescent properties indicated that 1 represents the first example of selective recognition toward cyano-containing molecules.
