近几十年来，人们一直在寻求一种适用于多种应用的可行介质。许多研究人员已尽最大努力来确定这种介质。最后，在此背景下，共轭聚合物因其多样化的性质已被证明是适用于各种应用的潜在平台。共轭聚合物主链由交替的电子供体和受体基团组成；这些化合物的性质可以通过改变共轭长度、相邻单体组、能级、分子相互作用等来调整。这种改变增加了光吸收范围，使分子成为一种光致发光活性材料，用于检测有毒金属离子、有机分子和气体检测器。能量转移、络合、电荷转移和活性化学转化是基于荧光的传感应用的常见机制。HOMO 和 LUMO 能级的优化已被用作共轭聚合物和分析物之间的有效电荷转移基，用于光致发光和电化学传感应用，并随后用于构建光电器件，如 NIR 传感器和柔性 OLED。高相容性共轭聚合物甚至使这些巨型分子易于模仿生物分子；一些化合物适用于抗菌应用，甚至用作药物输送系统。这篇评论文章旨在提供对共轭聚合物多功能应用的见解（2015 年至今），并提供所需的图示解释和单体的独特行为，包括芴、咔唑、苯基亚乙烯基、三苯胺、等等。因此，我们预测，这项工作将提供的共轭聚合物的整体应用的全面概述，提高其在多个域中包括便携式传感器，柔性光电器件和未来的药物递送过程的适用性。

Conjugated polymers – a versatile platform for various photophysical, electrochemical and biomedical applications: a comprehensive review

In recent decades, there has been a significant quest for a viable medium for multiple applications. Many researchers have devoted all their utmost efforts to identifying such a medium. Finally in this context, conjugated polymers have proven to be a potential platform for a variety of applications due to their diverse nature. The conjugated polymer backbone is made of alternate electron donor and acceptor groups; the properties of such compounds can be tuned by altering the length of conjugation, adjacent group of monomers, energy levels, molecular interaction, etc. This alteration increases the light absorbance range that enables the molecule to be a photoluminescence active material for sensing toxic metal ions, organic molecules and gas detectors. Energy transfer, complexation, charge transfer and active chemical transformations are the common mechanisms of fluorescence based sensing application. Optimization of the HOMO and LUMO levels has been used as an efficient charge transfer ground between a conjugated polymer and analyte for photoluminescence and electrochemical sensing applications, and has subsequently been used in the construction of optoelectronic devices such as NIR sensors and flexible OLEDs. High compatibility conjugated polymers even made these giant molecules apt for mimicking biomolecules; some compounds were suitable for anti-bacterial application and even served as a drug delivery system. This review article intends to provide insights (2015–present) into versatile applications of conjugated polymers with the required diagrammatic explanation and a unique behavior of monomers including fluorene, carbazole, phenyl vinylene, triphenylamine, etc. Thus, we predict that this work will offer a comprehensive overview of an overall application of conjugated polymers and improve their applicability in multiple domains including portable sensors, flexible optoelectronic devices and future drug delivery processes.
