Gold nanoparticles (AuNPs) are of considerable interest for diverse applications in areas such as medicine, catalysis, and sensing. AuNPs are generally surface-stabilized by organic matrices and coatings, and while the resultant organic compound (OC)/AuNP hybrids have been explored extensively, they are not suitable for certain applications (e.g. those necessitating reversible redox behaviour and/or long excited-state lifetimes), and they often suffer from low photo- and/or thermal stability. Transition metal complex (TMC)/AuNP hybrids have recently come to the fore as they circumvent some of the aforementioned shortcomings with OC/AuNP hybrids. This review summarizes progress thus far in the nascent field of TMC/AuNP hybrids. The structure and composition of extant TMC/AuNP hybrids are briefly reviewed and the range of TMCs employed in the shell of the hybrids are summarized, the one-phase, two-phase, and post-nanoparticle-synthesis synthetic methods to TMC/AuNP hybrids are discussed and contrasted, highlighting the advantages of variants of the last-mentioned procedure, and the utility of the various characterization techniques is discussed, emphasizing the need to employ multiple techniques in concert. Applications of TMC/AuNP hybrids in luminescence, electrochemical, and electro-optical sensing are described and critiqued, and their uses and potential in imaging, photo-dynamic therapy, nonlinear optics, and catalysis are assessed.

过渡金属络合物/金纳米颗粒杂化材料。

金纳米颗粒（AuNPs）对于医学，催化和传感等领域的各种应用引起了极大的兴趣。AuNP通常通过有机基质和涂料进行表面稳定处理，尽管对有机化合物（OC）/ AuNP杂化物进行了广泛的研究，但它们不适用于某些应用（例如需要可逆氧化还原行为和/或长激发态的应用）寿命），并且它们通常遭受低的光稳定性和/或热稳定性。过渡金属配合物（TMC）/ AuNP杂化剂最近由于OC / AuNP杂化剂克服了上述缺点而备受关注。这篇综述总结了迄今为止在TMC / AuNP杂种的新生领域中的进展。简要回顾了现存的TMC / AuNP杂种的结构和组成，总结了在杂种壳中使用的TMC的范围，总结了TMC / AuNP杂种的一相，两相和纳米粒子合成方法。讨论和对比，强调了最后提到的过程的变体的优点，并讨论了各种表征技术的实用性，强调了需要同时使用多种技术。描述并提出了TMC / AuNP混合体在发光，电化学和电光传感中的应用，并对其进行了评估，并评估了它们在成像，光动力疗法，非线性光学和催化方面的用途和潜力。讨论和对比了TMC / AuNP杂化剂的合成方法和纳米后合成方法，突出了最后提到的方法的变体的优点，并讨论了各种表征技术的实用性，强调需要同时使用多种技术。描述并提出了TMC / AuNP混合体在发光，电化学和电光传感中的应用，并对其进行了评估，并评估了它们在成像，光动力疗法，非线性光学和催化方面的用途和潜力。讨论和对比了TMC / AuNP杂化剂的合成方法和纳米后合成方法，突出了最后提到的方法的变体的优点，并讨论了各种表征技术的实用性，强调需要同时使用多种技术。描述并提出了TMC / AuNP杂化物在发光，电化学和光电传感中的应用，并对其进行了评述，并评估了它们在成像，光动力疗法，非线性光学和催化方面的用途和潜力。
