“…[10] The so-developed functional materials have as ultimate goal the preparation of valuable nanohybrids in which the merging of the intrinsic traits of the coupled constituents paves the way to advanced applications within the fields of optoelectronics, photovoltaics, medicinal chemistry, among others. [7,[11][12][13][14][15][16] To this aim, exerting chemical and constitutional control over the CND coupling with functional species is of paramount importance but it is still challenging. A possible solution to overcome this limitation might be the application of the molecular synthetic toolbox into the nanoscale level.…”

The surface of Carbon Nanodots (CNDs) stands as a rich chemical platform, able to regulate the interactions between particles and external species. Performing selective functionalization of these nanoscale entities is of practical importance, however, it still represents a considerable challenge. In this work, we exploited the organic chemistry toolbox to install target functionalities on the CND surface, while monitoring the chemical changes on the material's outer shell through nuclear magnetic resonance spectroscopy. Following this, we investigated the use of click chemistry to covalently connect CNDs of different nature en‐route towards covalent suprastructures with unprecedent molecular control. The different photophysical properties of the connected particles allowed their optical communication in the excited state. This work paves the way for the development of selective and addressable CND building blocks which can act as modular nanoscale synthons that mirror the long‐established reactivity of molecular organic synthesis.

Aggregation‐induced emission (AIE) is an intriguing photophysical phenomenon, where specific materials exhibit a remarkable surge in luminescence when brought together in non‐ideal solvents or within a solid matrix. Since the concept of AIE was first introduced in 2001, numerous advanced applications have been gradually explored across various domains, including optics, electronics, energy, and the life sciences. Of particular note is the growing interest in the application of AIE systems with near‐infrared (NIR) emissive feature in the field of biomedicine, encompassing detection, imaging, and therapeutic interventions. Notably, bibliometric analysis serves as a valuable tool to provide researchers with a comprehensive understanding of research achievements and developmental trends in specific fields, which is crucial for academic research. Herein, we present a general bibliometric overview spanning two decades of NIR‐AIE development. With the assistance of core scientific databases and various bibliometric software tools, we conducted a systematic analysis of annual publications and citations, the most influential countries/regions, leading authors, journals, and institutions, as well as the hot topics related to NIR applications and forward‐looking predictions. Furthermore, the application of AIE with NIR properties in the biomedical field is also systematically reviewed.
