“…Electron transfer (ET) smart materials, such as tunable luminescent and photochromic materials based on a host–guest platform, have attracted significant attention due to their potential applications in light sensing, detectors, information storage, anticounterfeiting, and others. − Various host–guest platforms have been documented through well-developed design and synthesis technology. − The luminescent and photochromic properties of the materials depend on their components and the interactions between hosts and guests. Consequently, researchers can exercise significant control over these and other chemical and physical properties.…”

The encapsulation of various guest molecules into the pores of metal−organic frameworks (MOFs) to form hybrid materials has attracted significant attention due to their unique spatial distribution and certain preferential geometry of the guests inside the MOFs. This arrangement often results in the guests exhibiting unique physical and chemical properties due to their intramolecular interactions with the host. In this article, five viologen derivatives were introduced as guests in a Zn-MOF with different benzene ring lengths, resulting in the formation of host−guest three-dimensional (3D) MOFs. The five compounds exhibited guest-dependent emission wavelength, color, and excellent photochromic behavior upon ultraviolet (UV) light radiation due to the distinct electronic transfer and π•••π stacking interactions between the viologen guests and the host framework. This study provides a host−guest strategy for designing color-tunable luminescent and highly sensitive photochromic materials.

“…Carbon nanomaterials, such as fullerene, graphene, graphdiyne and carbon nanotubes, have aroused much interest from scientists in recent years because of their distinctive structures as well as splendid electronic, optical and thermal performance 1‐3 . Carbon dots (CDs), as a kind of emerging carbon nanomaterials, which can be classified into carbonized polymer dots (CPDs), carbon quantum dots, carbon nanodots and graphene quantum dots, not only have the same fluorescence property as semiconductor quantum dots but also show many unique advantages including low toxicity, biocompatibility, chemical inertness, photostability and low cost 4‐6 . Consequently, CDs have been extensively studied and employed in many important fields like bioimaging, 7 photocatalysis, 8 electrocatalysis, 9 detection 10 and sensing 11 during the past decade.…”

We prepared carboxyl‐containing carbonized polymer dots (CPDs) with dual‐wavelength emission through a simple hydrothermal method. The CPDs emit blue light in live cells under the excitation at 405 nm, and show green fluorescence in cytoplasm and nucleoli when excited at 488 nm. No fluorescence can be seen in nuclei except nucleoli under the excitation at 488 nm, which means that the CPDs have excellent ability of labeling nucleoli in live cells with low background interference. This ability of the CPDs is derived from the aggregation induced by the hydrogen bonding between the carboxyl groups of the CPDs and the hydroxyl groups of ribonucleic acid at nucleoli. Fluorescence and cell culture passage experiments prove that the CPDs have no strong interaction with RNA, and all of them can be excreted out of cells in a couple of days. In vivo imaging for Caenorhabditis elegans indicates that the CPDs show the possibility of labeling nucleoli in live organisms in real‐time.
