New lanthanide carboxylate compounds with two- (2D) and three-dimensional (3D) structures have been prepared by employing 2,5-bis(prop-2-yn-1-yloxy)terephthalic acid (2,5-BPTA) as an organic linker. The compounds, [Ln(C14H8O6)(C7O3H4)·2H2O]·4(H2O), Ln = Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy [Ln(C7O3H4)3·(C3H7ON)·(H2O)]·2(H2O)(C3H7NO), La, Ce, structures, respectively. In all ions are connected together, forming a dimer, which is the 2,5-BPTA ligand. two-dimensional structure, there two moieties present, in three present. centers nine-coordinated, 2D structure has tricapped trigonal prismatic arrangement, 3D monocapped distorted square antiprismatic arrangement. Pr compound forms both whose formation depends on time of reaction (2 days─2D 5-6 days─3D). ligand emits blue region, using characteristic emission Eu3+ (red) Tb3+ (green) ions, we achieve white light (Y0.96Tb0.02Eu0.02) compound. overall quantum yield for 28%. strong green luminescence Tb3+-containing was employed to selectively sense Cr3+ Fe3+ aqueous solution limits detection (LODs) at 0.41 8.6 ppm, Tb found be good heterogeneous catalyst Ullman-type O-arylation between phenol bromoarene yields 95%. Magnetic studies Gd-, Tb-, Dy-containing showed weak exchange interactions within dimeric Ln2 units. present work demonstrates many utilities rare-earth-containing MOFs, especially toward white-light emission, metal-ion sensing, catalysis.

Dual Challenge–Response Systems of a Three-Dimensional “Bionic” Fluorescent Physically Unclonable Function Label

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(19), P. 25256 - 25267

Published: May 4, 2024

Inspired by the light and dark variations observed in natural cloud clusters under sunlight, we propose a three-dimensional (3D) "bionic" fluorescent physically unclonable function (PUF) label. The minimalist preparation process eliminates need for expensive traditional instruments, thus offering new insight into widespread adoption of 3D PUF labels. Eu(CCA)3(H2O)2 powder, which is first to its secondary building unit, was chosen as material. Its morphology preserved resin mimic cloud-like structures. Furthermore, luminescent properties are elucidated through experimental tests first-principles calculations. To overcome coding capacity limitation two-dimensional (2D) labels, dual challenge-response system model proposed. shallow deep models provide anticounterfeiting information from macro micro perspectives, respectively. This successfully increases encoding 210×10 2100×10000 10 × pixel binary code. Therefore, labels strike balance between simple usage enhanced label security.
