| Abstract: | "Three new luminescent metal-organic frameworks (LMOFs), [Zn(tppa)(ndc)] (n) (1), [Cd(tppa)(oba)] (n) (2), [Zn(2)(tppa)(bpdc)(2)] (n) (3) (tppa = tri(4-pyridylphenyl)amine, ndc = 1,4-naphthalenedicarboxylic acid, oba = 4,4'-oxydibenzoic acid, bpdc = 4,4'-biphenyldicarboxylic acid) have been synthesized by solvothermal method. Complexes 1 and 2 are 2-D two-fold interpenetrating structures, aligning into a 3-D structure through C-Hcdots, three dots, centeredpi stacking interactions, while 3 is a 5-fold interpenetrating three-dimensional structure. The internal quantum yields (IQYs) of complexes 1-3 are 32.7%, 45.7% and 24.0% (lambda (ex) = 365 nm), separately. Furthermore, all the complexes show different luminescence signal changes towards aromatic volatile organic compounds (AVOCs). Complex 1 exhibits a high sensitivity in the detection of both Fe(3+) and Cr(3+) with large quenching coefficients of K (sv) 2.57 x 10(4) M(-1) and 2.96 x 10(4) M(-1), respectively. All these results demonstrated potential applications in chemical sensing" |
