“…For HL 2Th , both QY and lifetime increase upon inclusion into polymer 1 (3.8 versus 4.2 % and 3.1 versus 5.2 ns for HL 2Th and 1 , respectively). This is in line with what is observed for other Zn II coordination polymers in the literature, where the luminescence efficiency increase is ascribed to the suppression of nonradiative decay processes, owing to the higher ligand conformational rigidity when included in the polymer . As for the other isomer, the opposite behavior is found: the QY and the lifetime are smaller in 2 than in HL 5Th (1.4 versus 0.6 % and 4.9 versus 2.1 ns for HL 5Th and 2 , respectively).…”

Two coordination polymers of assorted dimensionality (1D, 2D) have been prepared, namely [Zn3(L2Th)4(OH)2·2(HL2Th)]∞ (1) and [Zn(L5Th)(OAc)]∞ (2), starting from ZnII salts and the isomeric forms of the organic linker p‐(thiazolyl)benzoic acid: p‐(2‐thiazolyl)benzoic acid (HL2Th) and p‐(5‐thiazolyl)benzoic acid (HL5Th). The isomers have been prepared ad hoc, following straightforward Pd‐catalyzed C–C coupling reaction protocols. In 1, the deprotonated ligand is coordinated through its carboxylate group only, with dangling thiazole groups. The –COO– units are bridging adjacent metal centers, thus creating a 1D chain. The Zn3 cluster is made of one six‐coordinate (Oh) and two four‐coordinate (Td) ZnII ions; triple‐bridging µ3‐OH groups are balancing the overall positive charge. The structure of 2 is instead made of Zn2(carboxylate)4 “paddle‐wheel” dimers as the constituting inorganic node. The octahedral metal coordination sphere includes two µ‐(κ‐COO) benzoate spacers, two µ‐(κ‐COO) acetate ions, the thiazole N atoms coming from adjacent building blocks, and a weak Zn···Zn axial interaction. The resulting final assembly is two‐dimensional (2D), where p‐(5‐thiazolyl)benzoate adopts a genuine µ‐[κ(COO):κ(N)] bridging coordination mode. The luminescent properties of both polymers have been analyzed in the solid state; they feature ligand‐centered emissions at λ = 434 nm (1) and λ = 427 nm (2). These electronic transitions fall in the visible region, giving the samples a characteristic blue color under an ordinary UV lamp (excitation at λ = 254 nm). The theoretical analysis of the electronic features of the ligands and related molecular orbitals reveals that the observed transitions are mainly of π→π* nature, involving π orbitals delocalized on both aromatic cycles. A significant (reversible) blueshift of the emission maximum of ca. 60 nm, from the visible to the UV region, has been observed for 1 when suspended in water.

“…e transition metal compounds based on d 10 generally exhibited outstanding luminescent performances for the potential application of luminescence sensing [25,26]. Hence, in this work, the compounds' luminescent spectra were detected at RT, and with the aim of further under the luminescence nature, the luminescent spectra of associated free ligands were also gathered under identical conditions.…”

Two coordination polymers involving Cd(II), i.e., [Cd2(IDPA)2(bpe) (H2O)2]n·2n(H2O) (1) (H2IDPA is 5-(1-oxoisoindolin-2-yl)isophthalic acid, bpe is 1,2-bis(4-pyridyl)ethane, 4-bpmh is N, N-bis-pyridin-4-ylmethylene-hydrazine), and [Cd(IDPA)(4-bpmh)0.5(H2O)2]n·n(H2O) (2) are prepared under solvothermal conditions via tuning the auxiliary ligand from bpe to 4-bpmh. Moreover, the as-prepared complexes 1–2 reveal much stronger luminescence in contrast to that of the free organic ligands. Their preventive effect and mechanism on scar formation after cosmetic surgery was explored. First, the two complexes’ suppression of the viability of the human immortal keratinocyte line (HaCaT) cell line was examined via exploiting cell counting kit-8 (CCK-8) detection. The vascular endothelial growth factor (VEGF) signal pathway activation in HaCaT cells was detected by real-time reverse transcription-polymerase chain reaction (RT-PCR) assay.
