The integration of polymers, supramolecular macrocycles and aggregation‐induced emission (AIE) molecules provides numerous possibilities for constructing various functional supramolecular systems. Herein, we constructed supramolecular assembled systems based on discrete macrocyclic polymer hosts via the cooperation of hydra‐headed macrocycles containing two or three pillar[5]arene units (defined as P2, P3), the block polymer F127 and AIE molecules (alkyl‐cyano modified tetraphenylethene, alkyl‐triazole‐cyano modified 9,10‐distyrylanthracene, defined as TPE‐(CN)4 and DSA‐(TACN)2). Compared with the binary assembly between hydra‐headed hosts or F127 and AIE molecules, cascaded supramolecular assembly‐induced emission enhancement (SAIEE) in aqueous solution was achieved in discrete macrocyclic polymer‐based supramolecular assembled systems. Considering the cascaded SAIEE performance, we have successfully applied discrete macrocyclic polymer‐based supramolecular assembled systems to bioimaging and constructed an artificial light‐harvesting system (LHs) to explore more potential applications. The supramolecular assembly form of discrete macrocyclic polymers hosts and AIE molecules proposed in this work provides new inspiration for the construction and application of high‐performance supramolecular luminescent systems.

In recent years, there is a growing interest in developing ultralong organic room‐temperature phosphorescence (ORTP) with lifetimes in the range of seconds. As one of the important three primary colors, ultralong blue ORTP is an indispensable core component in RTP regulation and application, however, the large Stokes shift characteristics pose certain challenges in developing ultralong blue ORTP. Here, a new family of blue phosphors are synthesized and ultralong blue ORTP are realized through crystal assembly in water and organic phase. Remarkably, compared to crystal materials obtained in organic phases, assembly materials obtained in water enabled long‐lived blue ORTP with lifetimes up to 2.3 s and phosphorescence quantum yield reached as high as 29.27%. In addition to the efficient and green assembly form, such dark blue ORTP materials possessed high thermal stability and flexible tunability. Moreover, the superiority of the selected assembly components is demonstrated by comparing them with polymer assembly and the proposed blue ORTP materials show great potential in an organic programmable information encryption/anti‐counterfeiting.

Avoiding the tedious process of crystal cultivation and directly obtaining organic crystals with desirable phosphorescent performance is of great significance for studying their structure and properties. Herein, a set of benzophenone‐cored phosphors with bright green afterglow are obtained on a large scale through in‐situ generation via an end‐capping strategy to suppress non‐radiative triplet excitons and reinforce the intermolecular interactions. The ordered arrangement of phosphors with alkyl‐cyano groups as regulators is crucial for the enhancement of room‐temperature phosphorescence (RTP) emission, which has been further verified by the attenuated lifetimes in isolated states through the formation of inclusion complexes upon binding with pillar[5]arenes. Moreover, the hierarchical interactions of phosphors, including hydrogen bonding, π‐π stacking interactions, and van der Waals forces, are quantified by crystal structures and theoretical calculation to deeply interpret the origins of RTP emission. With this study, we provide a potential strategy for the direct acquisition of crystalline organic phosphors and modulation of RTP. [ABSTRACT FROM AUTHOR]

We report a novel tough self‐healing electrolyte on the basis of poly (acrylic acid‐co‐acrylamide) cross‐linked by divalent cobalt ions (Co2+) (P(AA‐co‐AAm)/CoCl2). Intermolecular and intramolecular hydrogen bonding work together with the metal‐coordination between Co2+ and carboxylic ions to form a hydrogel, which can resist various deformations. The hydrogel electrolyte exhibits excellent mechanical performance (elongation at break >1200 %, compressive stress >600 kPa and compressibility >90 %). The established supercapacitor based on P(AA‐co‐AAm)/CoCl2 can hold its capacitance even after bending, twisting, compressing and self‐healing. Moreover, it retains 90 % capacitance after 5000 cycles. Our electrolyte shows great prospects in manufacture of intelligent flexible equipment. Stretch it: A P(AA‐co‐AAm)/CoCl2 hydrogel is prepared as electrolyte that shows excellent stretchability and self‐healing ability. An electric double layer capacitor fabricated with the hydrogel electrolyte exhibits excellent flexibility,compressibility,and superior capacitance performance and cycle stability.
