Functional materials with multi-responsive properties and good controllability are highly desired for developing bioinspired intelligent multifunctional systems. Although some chromic molecules have been developed, it is still challenging to realize in situ multicolor fluorescence changes based on a single luminogen. Herein, we reported an aggregation-induced emission (AIE) luminogen called CPVCM, which can undergo specific amination primary amines trigger luminescence change photoarrangement under UV irradiation at the same active site.

ConspectusFluorescence is the emission of light following photon absorption. This optical phenomenon has many applications in daily life, such as LED lamps, forensics, and bioimaging. Traditionally, small-molecule fluorophores were most common, but types molecules particles with compelling fluorescence properties have expanded. For example, green fluorescent protein (GFP) was isolated from jellyfish won Nobel prize 2008 due to its significant utility a biomarker. Using intrinsic GFP, previously invisible biological processes substances can now be observed studied. Other materials also been developed, greatly expanding potential applications. Semiconductor quantum dots (QDs), which bright narrow bandwidth, are popular choice for display technologies. However, QDs made heavy metal elements Cd Se, pose safety concerns environment human health. Thus, new organic being developed mitigate toxicological while maintaining QD advantages.One type material attracting great attention an environmentally friendly substitute semiconductor carbon (CDs). CDs strong fluorescence, good photostability, low toxicity using variety precursors, some synthesis scale-up. since they through different methods, structure differ preparation preparation. There three major CDs: graphene (GQDs), (CQDs), amorphous or polymeric (PCDs). Account focuses on PCDs their unique by comparing it other CDs. The processes, properties, mechanisms, discussed below emphasis distinct attributes PCDs.PCDs synthesized small polymers. They cross-linked polymer fluorescence. possibly cross-link-enhanced clusteroluminescence that arises through-space interactions heteroatomic-rich functional groups. mechanisms CDs, including contributions core surface states, may contribute. profiles influenced chemical composition, functionalization, illumination. generally thought toxicity, this further improved removing toxic byproducts, functionalizing surface, reducing exposure minimize generation reactive oxygen species.

Abstract The luminescence materials act as the key components in many functional devices, well detection and imaging systems, which can be permeated each aspect of modern life, attract more attention for creative technology applications. In addition to diverse properties organic luminogens, multiple molecular packing at aggregated states frequently offers new and/or exciting performance. However, there still lacks comprehensive analysis these materials, resulting an increased gap between design practical this review, from basic knowledge compounds single molecules, discernable property excimer, charge transfer (CT) complex or self‐assembly systems by adjacent finally opto‐electronic performance aggregates, relevant factors applications are discussed.

Abstract Synthetic hydrogel strain sensors rarely exhibit a comprehensive combination of mechanical properties such as ultra‐stretchability, ultrafast self‐healing, and high sensitivity. Herein, seven small molecule enhanced behaviors polymer‐cluster based hydrogels are demonstrated. The oxidized polyethyleneimine/polymeric acrylic acid (ohPEI/PAA) with aromatic formic acids supramolecular cross‐linkers prepared by simultaneous formation ohPEI polymer clusters PAA upon the addition ammonium persulfate. optimized adhesive exhibits excellent properties, extensibility (up to 12 298%), real‐time self‐healing capability (<1 s, 93% efficiency), uniformity, underwater adhesivity, water‐sealing ability. proper binding strength skin (47 kPa) allows be utilized highly sensitive (gauge factor:16.08), conductive (2.58 mS cm −1 ), sensors. Specially, wood after dehydration is extremely high, reaching up 29.59 MPa. Additionally, when glycerol introduced, obtained gel maintains physical even at harsh‐temperature conditions (−40 80 °C). It presents that multiple hierarchical non‐covalent interactions including hydrogen bonding interactions, π–π stacking, electrostatic dipole–dipole clusters, allow for energy dissipation contribute performance hydrogel.
