We present the development of “all-in-one” layered Ln-MOFs (Ln-OXAL and Ln-GLYC; Ln = Tb, Eu) with efficient multicolor emission, multiple anticounterfeiting, and smart photoresponsive antibiotic properties. By controlling the energy transfer pathways, a series of multicolor emissions from chartreuse to red light were successfully achieved in Ln-MOFs. Furthermore, the typical fingerprint emission spectrum of Ln-MOFs with multicolor emission characteristics was utilized and further integrated into a high-capacity photonic barcode encoding library, and by employing an effective encoding strategy, a multilayered anticounterfeiting material with advanced information encryption capabilities was developed. Both Tb-OXAL and Tb-GLYC exhibit highly sensitive optical sensing abilities for detecting low concentrations of oxytetracycline, achieving limit of detection values as low as 1.35 and 7.44 μM, respectively. The integration of various applications in a specific material remains considerably challenging, primarily due to the inherent complexities in coordinating and ensuring compatibility among these varied properties.

调控能量转移途径构建多色发光镧系金属-有机框架及其多阶防伪条形码和抗生素传感


我们介绍了“一体化”层状 Ln-MOFs（Ln-OXAL 和 Ln-GLYC;Ln = Tb， Eu），具有高效的多色发射、多种防伪和智能光响应抗生素特性。通过控制能量转移途径，在 Ln-MOF 中成功实现了从黄绿色到红光的一系列多色发射。此外，利用具有多色发射特性的 Ln-MOF 的典型指纹发射光谱，并进一步集成到大容量光子条码编码库中，通过采用有效的编码策略，开发了一种具有高级信息加密能力的多层防伪材料。Tb-OXAL 和 Tb-GLYC 均表现出高灵敏度的光学传感能力，可检测低浓度的土霉素，检测限分别低至 1.35 μM 和 7.44 μM。将各种应用集成到特定材料中仍然极具挑战性，这主要是由于协调和确保这些不同特性之间的兼容性的固有复杂性。
