With the advent of the big data era, information storage and security are becoming increasingly important. However, high capacity information storage and multilevel anti-counterfeiting are typically difficult to achieve simultaneously. To address this challenge, herein, two electrochromic and electrofluorochromic dual-functional polymers with aggregation-induced emission (AIE) characteristics were rationally designed and facilely prepared. Upon applying voltages, the absorption and fluorescence ...

Two-way reversible shape memory polymers (2W-SMPs), capable of changing their shape reversibly, are highly desirable for many potential applications. However, the polymerization reactions used for preparing 2W-SMPs always require harsh conditions, such as metal catalysts, light irradiation and elevated temperature. Furthermore, there are few reports on SMPs that integrated with other functions, such as luminescence. Herein, luminescent 2W-SMPs of semi-crystalline PCL-based networks bearing an ag...

The amide bond is one of the most pivotal functional groups in chemistry and biology. It is also the key component of proteins and widely present in synthetic materials. The majority of studies have focused on the formation of the amide group, but its postmodification has scarcely been investigated. Herein, we successfully develop the Michael additions of amide to acrylate, acrylamide, or propiolate in the presence of phosphazene base at room temperature. This amide Michael addition is much more...

Facing the challenges posed by bacterial infection, it’s urgently needed for the real-time detection of bacterial infection combined with antibacterial functions. Herein, we prepare thermo- and pH-responsive poly(vinyl alcohol) derivatives (PVA-TPE) bearing aggregation-induced emission luminogens of tetraphenylethene (TPE) and quaternary ammonium moieties through a facile one-pot quaternization with tertiary amines method. Intrinsic fluorescence from TPE moieties and antibacterial functions from...

The research in advanced functional polymers is being driven by the fast-growing demand of new functional materials for revolutionary technologies. Polymers can be endowed with functions by the use of some special preparation methods or by introducing functional groups or fillers into materials. These functions are either possessed intrinsically by materials or actuated by external stimuli. In this review, we present an overview of the recent developments in research hotspots of functional polym...

Alkyne-based click polymerization has become a powerful tool for the preparation of functional polymers. However, the click polymerizations performed under mild reaction conditions should be further developed for more facile synthesis of functional polymeric materials. In this work, an efficient hydroxyl–yne click polymerization using ester activated alkynes and alcoholic hydroxyl groups as monomers is developed in the presence of a commercially available organobase bicyclo[2.2.2]-1,4-diazaoctan...

Abstract Shape memory polymers (SMPs) are capable of changing their shapes in a pre-defined manner under a stimulus, and have gained considerable interest in the past decades. Although a number of stimulus-responsive SMPs have been developed, thermally-induced SMPs are still the most common. This review presents the concepts, the programming procedures, the molecular mechanism, classification, design strategies and the recent progress of thermally-induced SMPs, including dual, triple, multiple S...

Bubbling carbon dioxide (CO2) into aqueous solutions of bile salts such as sodium deoxycholate caused a gelation of the solution, forming a hydrogel made of entirely natural biological molecules and providing a convenient storage reservoir of CO2 in water. The carboxylate group of the bile salt becomes protonated in the aqueous solutions to make the bile acid only marginally soluble in water, which induces the formation of a supramolecular hydrogel with nanofibrous structures. Such hydrogels sho...

Two-way reversible shape memory polymers (2W-SMPs), especially those that are light-responsive, are highly desirable for many applications, especially in the biomedical field, because of the convenience of indirect heating. We have designed and prepared a series of light-actuated 2W-SMP composites by incorporating very small amounts of polydopamine (PDA) nanospheres into semicrystalline polymer networks based on biodegradable poly(e-caprolactone) copolymers. PDA nanospheres can be well dispersed...
