Both pillar[n]arenes (P[n]As) and [n]cycloparaphenylenes ([n]CPPs) play an important role in supramolecular chemistry. Herein, we report the precise synthesis of two multifunctional bismacrocycles [n]CPP-P[5]A by integrating P[5]A into [n]CPP backbone. The photoluminescence quantum yield (ΦF ) was found to show a dramatic increase relative corresponding [n]CPPs. chiral enantiomers (pR)/(pS)-[8]CPP-P[5]A were successfully isolated HPLC, showed promising properties circularly polarized...
Optical information encryption is closely related to security, and smart hydrogels with tunable optical properties under external stimuli have received much attention as storage materials. However, it still challenging achieve complex camouflage large-capacity in hydrogel systems. Herein, a hybrid encoding strategy afforded by an aggregation-induced emission (AIE) fluorescent multi-stimuli responsiveness pioneered feasible alternative for multiple strategies. More specifically, the...
In situ polymer gels have been received as a useful tool for sealing operations such fluid loss control during well drilling and workover completion, stimulation, water shutoff, wellbore integrity, pressure management. With the development of deep-sea, deep-earth, unconventional reservoirs, various harsh conditions high temperature, pressure, complex working pose great challenges to performance gels. This paper first summarizes application operating mechanism in near-wellbore zones. Then,...
The introduction of dynamic covalent bonds into shape memory polymers (SMPs) has offered the possibility reprocessing, but multifunctional modifications have not been sufficiently investigated. This work reported photoluminescence thermadapt two-way SMPs (2W-SMPs) based on syndiotactic 1,2-polybutadiene (SPB). ZnS:Cu particles were modified to form β-hydroxyester with epoxidized SPB (ESPB), and a reversible cross-linked network was constructed inside polymer. crystallization–melting...
Polymer gels have been accepted as a useful tool to address many sealing operations such drilling and completion, well stimulation, wellbore integrity, water gas shutoff, etc. Previously, we developed an ultra-high strength gel (USGel) for medium ultra-low temperature reservoirs. However, the removal of USGel is difficult problem most temporary plugging operations. This paper first provides new insights into mechanism USGel, where multistage network structure physical entanglement are main...
Shape memory polymers (SMPs), as a type of smart material, play significant role in practical applications. Unlike the hot programming SMPs, cold SMPs does not require preheating. They can undergo deformation and fix temporary shape at specific temperature be restored upon heating. typically internal cross-linking to "remember" their permanent shape. However, cross-linked materials cannot recycled, resulting resource waste environmental pollution. Drawing inspiration from dynamic covalent...

Abstract The rapid development of photochromic devices has stimulated great enthusiasm for the design and preparation luminescent materials. Introducing fluorescent powder ZnS:Cu into cross‐linked polymer matrix is an efficient simple method to obtain materials with excellent comprehensive performance. However, traditional directly introduce by physical mixing. This not only increases internal defects reduces mechanical properties, but also hinders from absorbing external energy its...
Abstract Fluorescent hydrogels are soft materials that can emit light under certain conditions, which makes them attractive for biomedical and engineering applications. Nevertheless, one of the major challenges in developing fluorescent is their low mechanical properties. To overcome this challenge, we have developed an efficient method preparing high‐strength fluorescence via freeze–thaw cycles. This approach offers a promising solution to enhance properties hydrogels, could broaden...
Abstract The rapid advances in photochromic devices have spurred great enthusiasm the design and preparation of luminescent materials. It is an efficient facile strategy to incorporate ZnS‐based phosphors into crosslinking polymer substrates, obtaining materials with excellent comprehensive properties. However, polymeric phosphor luminous are unable be recycled reprocess at end service, limiting their long‐term utilization burdening environment. Besides, few reported works explored...
