Cucurbit[n]urils (Q[n]s or CB[n]s), as a classical of artificial organic macrocyclic hosts, were found to have excellent advantages in the fabricating tunable and smart luminescent materials aqueous media solid state with high emitting efficiency under rigid pumpkin-shaped structure-derived macrocyclic-confinement effect recent years. This review aims give systematically up-to-date overview Q[n]-based supramolecular emissions from confined spaces triggered host–guest complexes, including assembly fashions mechanisms macrocycle-based well their applications. Finally, challenges outlook are provided. Since this class emissions, which essentially derived cavity-dependent confinement resulting fashions, emerged only few years ago, we hope will provide valuable information for further development light-emitting other related research fields.

Abstract The excited‐state tuning of luminescent metal–organic compounds has made great progress in the fields optical imaging, photocatalysis, photodynamic therapy, light‐emitting devices, sensors, and so on. Although with high luminescence efficiency can be realized via enhanced molecular rigidity heavy‐atom effect, their corresponding lifetimes are still limited on order a nanosecond to millisecond, owing inherent competition between luminous lifetime. Therefore, advanced applications (i.e., persistent afterglow information security, anti‐counterfeiting, smart materials, among others) related long (LPL, typically lifetime larger than millisecond) seriously hindered. This review gives timely systematic summary for realizing room‐temperature phosphorescence (RTP)‐type thermally activated delayed fluorescence (TADF)‐type LPL during last few years. Particularly, based perspectives time, space, energy dimensions, fundamental materials design coordination assembly systematically described first time. Moreover, internal external factors influencing properties terms efficiency, lifetime, color illustrated. Last but not least, challenges also discussed developing from compounds.

Some important biological species and microenvironments maintain a complex delicate dynamic balance in life systems, participating the regulation of various physiological processes playing indispensable roles maintaining healthy development living bodies. Disruption their homeostasis organisms can cause diseases even death. Therefore, real time monitoring these during different pathological is great significance. Fluorescent-probe-based techniques have been recognized as one most powerful tools for imaging samples. In this Account, we introduce representative works from our group field fluorescent probes capable detecting metal ions, small bioactive molecules, microenvironment. The design strategies molecule applications will be discussed. By regulating strategy mechanism (e.g., ICT, PeT, FRET) electronic spectral characteristics platforms, chemical show high selectivity diverse functions, which used processes. Through exploration rational response strategy, combined with variety techniques, such super-resolution imaging, photoacoustic (PA) etc., realized multimode analytes subcellular level to vivo level, provides means study functions microenvironments.

Abstract Near‐infrared (NIR) absorbing materials hold great potential in biomedical applications, such as fluorescence imaging (FLI), photoacoustic (PAI), photodynamic therapy (PDT), and photothermal (PTT). Generally, these can be classified into two main categories based on their wavelengths: the first NIR (NIR‐I) (~650–950 nm) second (NIR‐II) (~1000–1700 materials. Due to reduced absorption scattering of NIR‐II light tissue compared NIR‐I light, enable with improved contrast deepened penetration, which is favor practical applications. Various inorganic have been developed for phototheranostics recent years. However, non‐biodegradability toxicity hinder further clinical translation. Biocompatible organic biodegradability well tailored optical property are thus more desired. In this review, we summarize advances nanoagents (ONAs) small molecules (SMs) conjugated polymers (CPs) PAI PTT show our perspectives future challenges development

Since the last century, we have witnessed development of molecular magnetism which deals with magnetic materials based on species, i.e., organic radicals and metal complexes. Among them, broadest attention was devoted to molecule-based ferro-/ferrimagnets, spin transition materials, including those exploring electron transfer, nanomagnets, such as single-molecule magnets (SMMs), qubits, stimuli-responsive materials. Their physical properties open application horizons in sensors, data storage, spintronics, quantum computation. It found that various optical phenomena, thermochromism, photoswitching characteristics, luminescence, nonlinear chiroptical effects, well responsivity external stimuli, can be implemented into Moreover, fruitful interactions these effects provide new cross-effects multifunctionality, enriching applications optical, electronic, devices. This Review aims show scope phenomena generated recent advances areas high-temperature photomagnetism, thermometry utilizing SMMs, addressability magneto-chiral dichroism, opto-magneto-electric multifunctionality.

Neurotransmitters are important signaling molecules in the brain and relevant many diseases. Measuring them with high spatial temporal resolutions biological systems is challenging. Here, we develop a ratiometric fluorescent sensor/probe for catecholamine neurotransmitters on basis of near-infrared (NIR) semiconducting single wall carbon nanotubes (SWCNTs). Phenylboronic acid (PBA)-based quantum defects incorporated into to interact selectively catechol moieties. These PBA-SWCNTs further modified poly(ethylene glycol) phospholipids (PEG-PL) biocompatibility. Catecholamines, including dopamine, do not affect intrinsic E11 fluorescence (990 nm) these (PEG-PL-PBA-SWCNT) sensors. In contrast, defect-related E11* emission (1130 decreases by up 35%. Furthermore, this dual functionalization allows tuning selectivity changing charge PEG polymer. sensors taken cells, which beneficial extracellular imaging, they functional slices. summary, use SWCNTs create biosensor dopamine.
