Organic quantum materials: A review

Abstract

Interests in organic quantum materials (OQMs) have been explosively growing in the field of condensed physics of matter due to their rich chemistry and unique quantum properties. They are strongly correlated systems and show novel electromagnetic performance such as high‐temperature superconducting, quantum sensing, spin electronics, quantum dots, topological insulating, quantum Hall effects, spin liquids, qubits, and so forth, which exhibit promising prospects in information communication and thus facilitate the construction of a modern intelligent society. This article reviews recent developments in the research on the electromagnetic characteristics of OQMs. We mainly give an overview on the progress of superconductors and quantum spin liquids based on organic materials and describe their possible mechanisms. Numerous experimental findings exhibit new exciton interactions and provide insights into exotic electronic properties. Finally, their association and strategies for realizing multiple quantum states in one system are discussed.

MXene-based wearable supercapacitors and their transformative impact on healthcare

“…138 Achieving mechanical flexibility in MXene-based supercapacitors involves designing suitable flexible substrates, electrode materials, and binder systems. 33,108…”

“…[29][30][31] A wide variety of MXene-based composites with excellent volumetric capacitance, high mechanical flexibility, good electrochemical performance, and high energy density have been employed to fabricate supercapacitors. 32,33 Herein, the current trends, main challenges, and future prospects for the deployment of MXenes and their composites in manufacturing wearable supercapacitors are deliberated.…”

Facile fabrication of PANI/g-C3N4/MXene composites as electrode materials for supercapacitors

“…MXene is a class of transition metal carbides, carbonitrides or nitrides with a two-dimensional structure, which possesses unique structures, electrical properties and large specific surface areas. [15][16][17][18] When used as electrode materials of SCs, the introduction of MXene into composites further enhances the conductivity of the composites and thus facilitates electron transfer. [19][20][21] For example, Wu et al found that ultrathin Ti 3 C 2 nanosheets can provide good mechanical stability, high conductivity and more active sites to the Ti 3 C 2 /PANI composite.…”

Acoustic platforms meet MXenes – a new paradigm shift in the palette of biomedical applications

“…57,58 However, other MXenes such as Nb 2 CT x , Mo 2 CT x , and Ta 4 C 3 T x are also explored for various applications including acoustic applications. 59,60 The synthetic routes of MXenes mainly revolve around three different etching methods for removing the A layer from their corresponding MAX phases. The first and most commonly employed method is the hydrofluoric acid (HF) etching method by reacting the MAX phase in 48% HF for several hours (varies 24-96 h) at room temperature.…”
