摘要

共价有机框架(COFs)具有一系列优异的特性,包括显著的多孔性、出色的稳定性和精确调整的 π 共轭网络,使其成为极有希望应用于荧光传感器的候选材料。在本研究中,我们合成了两种用于肼检测的肼连接 COF。腙连接的部分共轭结构有效地减弱了聚集引起的荧光淬灭过程。此外,柔性结构成分的加入进一步减少了共轭,从而提高了发光效率。值得注意的是,这些 COFs 具有大量杂原子,能与肼分子发生独特的相互作用,进而提高了肼检测的选择性和灵敏度。这些 COFs 的检测限达到纳摩尔范围,超过了之前报道的所有 COFs,从而凸显了它们在化学传感应用中的卓越性能。

Emissive Hydrazone-Linked Covalent Organic Frameworks as Highly Sensitive and Selective Sensor for the Hydrazine Detection.

Covalent Organic Frameworks (COFs) exhibit a range of exceptional attributes, including notable porosity, outstanding stability, and a precisely tuned π-conjugated network, rendering them highly promising candidates for fluorescence sensors applications. In this study, the synthesis of two emissive hydrazone-linked COFs designed for hydrazine detection is presented. The partially conjugated structure of the hydrazone linkage effectively weakens the fluorescence quenching processes induced by aggregation. Additionally, the incorporation of flexible structural components further reduces conjugation, thereby enhancing luminescent efficiency. Remarkably, these COFs possess a significant abundance of heteroatoms, enabling distinctive interactions with hydrazine molecules, which in turn results in exceptional selectivity and sensitivity for hydrazine detection. The detection limit of these COFs reaches the nanomolar range, surpassing all previously reported COFs, thereby underscoring their superior performance in chemical sensing applications.
