ABSTRACT A two‐dimensional (2D) zinc(II) coordination polymer CP‐1 , [Zn(im 2 bod)(bdc)] n (im bod = 4,6‐bis(imidazol‐1‐yl)‐2,1,3‐benzoxadiazole, bdc 2− 1,4‐benzenedicarboxylate), was synthesized and fully characterized. crystallizes in the monoclinic crystal system, space group P 1 /n. Zn 2+ ions adopt a four‐coordinated distorted tetrahedral geometry. The structure of comprises layer consisting cations connected by im ligands. adjutant layers participate π‐π stacking interactions via benzene 2,1,3‐benzoxadiazole rings. demonstrated blue emission with maximum at 490 nm photoluminescence quantum yield 24%. Luminescent sensing properties aqueous suspension toward metal were evaluated, selective quenching response observed Ga 3+ limit detection 10 μM.

ABSTRACT One‐dimensional coordination polymer La‐CP , {[La(H 2 O) (HL O ) (L )]·H O} n containing a new luminescent ligand 4,7‐di(4‐carboxypyrazol‐1‐yl)‐2,1,3‐benzoxadiazole (H L was synthesized. Upon excitation at 400 nm, the compound shows strong emission with maximum 550 nm high photoluminescence quantum yield of 43%. demonstrates sensing properties toward aluminum and gallium cations, as well dihydrogen phosphate sulfate anions through enhancement response. The limits detection were 0.42, 0.70, 0.37, 0.40 μM, respectively. is first example sensor for anion among all types polymers. uptake analytes under conditions evaluated, absorption result such proposed probable response mechanism.

This work contributes to luminescent molecular switches featuring several emission pathways, which can be activated by external stimuli. We designed Zn complexes with phenylbenzothiazole-based α-aminomethylphosphine oxide (L) and isolated them as crystalline phases, α-[ZnL2Cl2], [ZnL(EtOAc)Cl2], [ZnL2Cl2]·1.5CH2Cl2, [ZnL2Cl2]·1.5CHCl3. They feature an intramolecular hydrogen bond of medium strength, capable excited-state proton transfer (ESIPT), well able for intersystem crossing between singlet triplet states. Since neither these processes is predominant, one or the other occur depending on a slight change in geometry. The phases reveal red-colored ESIPT fluorescence, while metastable amorphous phase β-[ZnL2Cl2] similar structure coordination center reveals yellow-colored room-temperature phosphorescence. Combined experimental quantum-chemical TD-DFT study clarified dual behavior polymorphs α-[ZnL2Cl2] β-[ZnL2Cl2], attributed high dependence probability geometry phenylbenzothiazole moiety. reversible transition, accompanied mechanism (ESIPT fluorescence vs phosphorescence), manipulated fuming CHCl3 Et2O, respectively. have demonstrated good adhesive properties polymer-free film toward glass plastic, naked-eye color response easy recovery CHCl3.
