Abstract

Microporous structures have attracted significant attention in recent years. In particular, metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have received considerable attention due to their tailorable structures that offer a wide range of choices in terms of molecular building blocks. Due to their high tunability, these materials are considered as ideal host matrices for templating and encapsulating guest materials, particularly quantum dots (QDs). QDs are investigated heavily for various applications such as light-emitting diodes (LED), biosensors, catalysts, and solar cells due to their unique properties from the quantum confinement effect. However, one of the drawbacks of QDs is their tendency to aggregate and exhibit low stability due to their small size and kinetic trapping in nanoparticle form. This perspective highlights promising approaches to enhance the performance and stability of QDs by using microporous materials as an encapsulation layer. Additionally, potential mitigating strategies are discussed to overcome current challenges and improve the practicality of QDs embedded in microporous nanocomposites.

新兴微孔材料作为量子点的新模板

近年来，微孔结构引起了人们的广泛关注。特别是金属有机框架(MOFs)和共价有机框架(COFs)由于其可定制的结构提供了广泛的分子构建模块选择而受到了相当大的关注。由于其高可调性，这些材料被认为是模板化和封装客体材料，特别是量子点(QDs)的理想宿主矩阵。由于量子限制效应的独特性质，量子点在发光二极管(LED)、生物传感器、催化剂和太阳能电池等各种应用中得到了广泛的研究。然而，量子点的缺点之一是由于它们的小尺寸和纳米颗粒形式的动力学捕获，它们倾向于聚集和表现出低稳定性。这一观点强调了利用微孔材料作为封装层来提高量子点性能和稳定性的有希望的方法。此外，讨论了潜在的缓解策略，以克服当前的挑战，提高嵌入微孔纳米复合材料的量子点的实用性。

期刊介绍： Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover: • Novel micro and nanostructures • Nanomaterials (nanowires, nanodots, 2D materials ) and devices • Synthetic heterostructures • Plasmonics • Micro and nano-defects in materials (semiconductor, metal and insulators) • Surfaces and interfaces of thin films In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
