Cellulose nanocrystals (CNCs) have attracted growing interest in optics and electronics, extending beyond their traditional applications. They are considered key materials due to their fast computing, sensing adhesion, and emission of circularly polarized luminescence with high dissymmetry factors. This interest arises from their unique chemical structure, which gives rise to structural color, a chiral nematic phase, and high mechanical strength. In this perspective, we first introduce the definition, sources, and fundamental properties of CNCs to explain the basis for their unique and effective use in optics and electronics. Next, we review recent research on the application of CNCs in these fields. We then analyze the current limitations that hinder further advancement. Finally, we offer our own perspective on future directions for the CNC-enabled advanced optics and electronics.
纤维素纳米晶体（CNCs）在光学和电子领域引起了越来越多的关注，其应用范围已超越传统领域。由于它们具有快速计算、传感粘附以及发射具有高不对称因子的圆偏振发光特性，因此被视为关键材料。这种关注源于其独特的化学结构，该结构可产生结构色、手性向列相和高机械强度。从这个角度出发，我们首先介绍纤维素纳米晶体的定义、来源和基本特性，以解释其在光学和电子领域独特而有效应用的基础。接下来，我们回顾纤维素纳米晶体在这些领域应用的最新研究。然后，我们分析阻碍进一步发展的当前限制因素。最后，我们就基于纤维素纳米晶体的先进光学和电子学的未来发展方向提出自己的观点。
