“…The material could be imparted with intriguing properties such as self‐repairing and chirality via incorporation of supramolecular recognition motifs. [ 1‐4 ] 2‐Ureido‐4[1 H ]‐pyrimidinone (UPy) is a well‐explored supramolecular building block that can form robust dimer through quadruple hydrogen bonds. Owing to the high binding constant and ease of synthesis, UPy has been widely used to construct supramolecular polymers with self‐healing, shape memory properties as well as enhanced mechanical performances.…”

Comprehensive SummaryCarbon dots (CDs) are an emerging class of nanomaterials with intriguing photophysical properties. Recently, achieving room temperature phosphorescence (RTP) for CDs has attracted considerable attention for biomedical and information applications. However, the CDs based RTP materials generally require the use of polymeric and inorganic matrix to provide the rigid environments, which remains a great challenge to obtain matrix‐free CDs with RTP. Herein, a novel supramolecular strategy based on strong interparticle interactions has been developed to attain this objective, by covalent decoration of ureido‐pyrimidinone (UPy, a multiple hydrogen bonding unit) on the surface of CDs. Structural characterizations validated the core‐shell structure of the as‐prepared CDs (EDTA‐CDs) and demonstrated the successful attachment of UPy via post‐modification (UPy‐CDs). The presence of UPy recognition units render the strong hydrogen bonding between UPy‐CDs, which stabilizes the triplet state via rigidifying effect. As a result, UPy‐CDs exhibit matrix‐free efficient RTP (λem = 534 nm) with high brightness and long lifetime (33.6 ms) in the solid state. Owing to the dual‐emission character, we further explored the application potential of UPy‐CDs in information encryption and anti‐counterfeiting. Overall, this work provides a new and facile strategy for achieving matrix‐free phosphorescent CDs with elegant incorporation of supramolecular chemistry.

“…[3,4] This is why SPNs have been widely utilized in a number of fields including self-healing materials, memory materials, expansion molding materials, adhesives and information storage. [5][6][7] Classifying according to the type of non-covalent interactions, the driving forces forming SPNs encompass hydrogen bonding, metal coordination, π-π donor-acceptor effects, host-guest recognition, etc. [8][9][10][11][12] In particular, different from other types, host-guest recognition often contains multiple non-covalent interactions.…”

Supramolecular polymer networks (SPNs) based on pillar [n]arene are widely studied and it is known that evolution from linear polymers to SPNs occurs as a progressive process, which is of importance to monitor the detailed morphology throughout the process. Yet, the current reports related to that distinction by employing fluorescence approach have realized confined success, it still remains a challenge to distinguish the various states visually. Herein, a fluorescent group of the pyrene benzohydrazonate-based (PBHZ-based) derivative is introduced into the pillar[5]arene based SPNs gained from host-guest recognition, enabling the visual monitoring during the formation of SPNs. The whole visual detection was based on the fluorescence color transition ranging from blue to green relying on the gradual aggregated PBHZ molecules upon the increasing cross-linking degree. Besides, the stimuli-responsiveness of this SPNs was confirmed that increasing the temperature or adding a reducing agent would reduce the cross-linking degree.

Photoactives have a wide variety of applications that can benefit human health including the prevention of melanoma and in photodynamic therapy. However, they have also been implicated in potential adverse impacts on the aquatic environment. Hence, several efforts have been made to either synthesize or to modulate properties of existing photoactives. Supramolecular modification is one of the ways in which photoactives are complexed with macrocycles to yield unique physical and chemical properties. Confined cavities of macrocycles have the potential to alter the life span of photoactive intermediates and thereby their applications. In this review, we have discussed the complexation of photoactives within select macrocycles, including calixarenes, curcurbit[n]urils, cyclodextrins, bis‐urea and octa‐acid. The comprehensive review gives an overview of how self‐assembly through non‐covalent interactions have enabled formation of inclusion complexes with improved photo stability and reduced phototoxicity. It also discusses how this technology may be leveraged in the future to counter the possible negative effects of photoactives.
