Conjugated microporous polymers (CMPs) are of great interest because these types materials have high specific surface area and pore diameters less than 2 nm. CMPs found applications in the fields hydrogen storage, heterogeneous catalysts, gas-permeable membranes light-emitting organics. A large number recent reports demonstrated that can be prepared using several approaches like noble metal-mediated ethynyl, Sonogashira–Hagihara coupling, Suzuki coupling Yamamoto reactions. In this review,...

Converting waste into versatile materials has been considered as an effective strategy to tackle environmental issues such shortages in food, clean water, and energy. Conventional carbonization technology provided approach for constructing photothermal interfacial evaporation or crude oil removal. However, high energy consumption, poor shape retention, weak mechanical strength have significantly hindered the practical application of conventional technology. This work discusses how a...

Abstract Morphological information encryption such as gesture and sign language is a traditional but efficient way of storage communication. However, due to the limited deformability, almost all existing materials store deliver via pattern or color changes on 2D plane. Herein, thermo ion dual‐responsive shape memory hydrogel containing short alkyl chains modified polyvinyl alcohol (PVA‐C6) polyacrylamide‐co‐polyacrylic acid [P(AAm‐co‐AAc)], prepared. In this system, ion‐responsive process...

The built-in electric field (BEF) has been considered as the key kinetic factor for facilitating efficient photoinduced carrier separation and migration of polymeric photocatalysts. Enhancing BEF polymers could enable a directional photogenerated carriers to accelerate charge thus boost photocatalytic performances. However, achieving this approach remains formidable challenge, which never realized in conjugated microporous (CMPs). Herein, we developed molecular dipole control strategy...

Abstract As one of the severe global problems, counterfeiting information has brought a huge negative impact on every aspect human society. Though various anticounterfeiting strategies, including fluorescent materials, are widely developed for dealing with above problem, security level needs to be further improved due sophisticated hacking techniques. In this study, an organohydrogel is designed by constructing interpenetrating networks, in which naphthalimide moieties (DEAN, green‐yellow...

Abstract Stevia ( rebaudiana Bertoni) is well known for its very sweet steviol glycosides (SGs) consisting of a common tetracyclic diterpenoid backbone and variable glycone. Steviol are 150–300 times sweeter than sucrose used as natural zero-calorie sweeteners. However, the most promising compounds biosynthesized in small amounts. Based on Illumina, PacBio, Hi-C sequencing, we constructed chromosome-level assembly covering 1416 Mb with contig N50 value 616.85 kb scaffold 106.55 Mb. More...
