“…5d). Furthermore, the K SV value was calculated to be 7.71 × 10 5 M − 1 by formula (1) I 0 /I = K sv [Q] + 1 [39][40] (where I 0 is the initial luminescence intensity; I is the luminescence intensity of the analyte; [Q] is the concentration of the analyte; and K SV is the Stern − Volmer quenching), and the limit of detection (LOD) was calculated to be 4.42 nM by formula (2) 3σ/slope [41] (where σ represents the standard error).…”

A new 2D homochiral zinc coordination polymer (Zn-CP) with 52-member rings was synthesized by solvothermal method. X-ray single crystal diffraction results show that the initial ligand (H2ibga = (4-(1H-imidazol-1-yl)benzyl)-L-glutamic acid) cyclized and crystallized in monoclinic with space group P2 after coordination with zinc(II) ions. Phase purity and thermal stability of Zn-CP were verified by X-ray powder diffraction (PXRD) and thermogravimetric (TG), respectively. Additionally, Zn-CP can recognize tetracycline (TC), Fe3+ and ascorbic acid (AA) rapidly and selectively in aqueous solution, with low detection limits (LODs) of 3.49 nM, 4.42 nM and 0.38 µM, respectively. The detection mechanisms have been investigated in detail.

Mononuclear Zn(II) compounds, [Zn(L1)](ClO4)2 (1) and [Zn(L2)](ClO4)2 (2), embedded with ligands, L1=N1‐(pyridin‐2‐ylmethyl)‐N2‐(2‐((pyridin‐2‐ylmethyl)amino)ethyl)ethane‐1,2‐diamine and L2=N1‐(pyridin‐2‐ylmethyl)‐N3‐(3‐((pyridin‐2‐ylmethyl)amino)propyl)propane‐1,3‐diamine are synthesized. Compound 1 is revisited, and structure‐function relation is compared with new compound 2. Single crystal X‐ray analysis revealed that compound 1 crystallizes in the tetragonal non‐centrosymmetric P41 space group while 2 crystallizes in a centrosymmetric monoclinic space group P21/c. The asymmetric unit consists of a crystallographically independent [Zn(L1)]2+cation in 1 while [Zn(L2)]2+cation in 2 and two unique perchlorate anions in both. IR spectra of 1 and 2 confirmed the vibrations due to organic ligands and tetrahedral perchlorates. PXRD confirmed the phase purity of powdered samples compared with theoretical PXRD patterns obtained from single‐crystal X‐ray diffraction data. NMR and ESI‐MS data suggested the phase purity and stability of compounds 1 and 2 in solution. Photoluminescence properties of compounds 1 and 2 have been investigated, considering their application in sensing explosive nitroaromatic compounds. Our results suggest that compound 1 is very selective in the chemical sensing of trinitrophenol (TNP) and dinitrophenol (DNP) in an aqueous medium compared to the reactivity of compound 2. The existence of spectral overlap in the absorption spectra of 2,4‐dinitrophenol (DNP) and 2,4,6‐trinitrophenol (TNP) with the emission spectrum of 1 or 2 indicates the operation of the resonance electron transfer (RET) mechanism.

The highly sensitive detection of carcinogenic pollutant 2,4,6‐trinitrophenol (PA) is of great significance for environmental protection and human health. Based on the organic building block 1,3,6,8‐tetrakis (p‐benzoic acid) pyrene (H4TBAPy), the porous nano‐scale hydrogen‐bonded organic framework material (PFC‐1) was successfully synthesized. The large π‐π conjugated structure makes it to show excellent fluorescence characteristics. PFC‐1 showed excellent selective fluorescence detection for PA. PFC‐1 exhibited significant quenching effect upon the addition of PA. The quenching efficiency Ksv of PFC‐1 material for PA is 9.14×104 M−1 and the limit of detection (LOD) reaches 0.75 μM. PFC‐1 exhibits excellent fluorescence sensing performance for PA, which greatly expands the potential application of hydrogen‐bonded organic framework materials in the field of fluorescence sensing.
