Herein, an all‐solid‐state sequential self‐organization and self‐assembly process is reported for the in situ construction of a color tunable luminous inorganic/polymer hybrid with high direct piezoresponse. The primary inorganic self‐organization in solid polymer and the subsequent polymer self‐assembly are achieved at high pressure with the first utilization of piezo‐copolymer (PVDF‐TrFE) as the host matrix of guest carbon quantum dots (CQDs). This process induces the spontaneous formation of a highly ordered, microscale, polygonal, and hierarchically structured CQDs/PVDF‐TrFE hybrid with multicolor photoluminescence, consisting of very thermodynamic stable polar crystalline nanowire arrays. The electrical polarization‐free CQDs/PVDF‐TrFE hybrids can efficiently harvest the environmental available kinetic mechanical energy with a new large‐scale group‐cooperation mechanism. The open‐circuit voltage and short‐circuit current outputs reach up to 29.6 V cm−2 and 550 nA cm−2, respectively. The CQDs/PVDF‐TrFE–based hybrid nanogenerator demonstrates drastically improved durable and reliable features during the real‐time demonstration of powering commercial light emitting diodes. No attenuation/fluctuation of the electrical signals is observed for ≈10 000 continuous working cycles. This study may offer a new design concept for progressively but spontaneously constructing novel multiple self‐adaptive complex inorganic/polymer hybrids that promise applications in the next generation of self‐powered autonomous optoelectronic devices.

Aliphatic polymers, such as polypropylene, styrene ethylene butylene styrene and norbornene, which show great alkaline stability and flexibility, have become the main research trend of the skeleton of anion exchange membranes. Here, we prepared a copolymer with all carbon atoms on the main chain. Firstly, a new vinylimidazole cationic monomer was prepared, and then copolymerized with styrene and acrylonitrile to obtain a copolymer (PASIm). Furthermore, (2,6-dimethyl-1,4-phenylene oxide) (PPO) was introduced to cross-link with PSAIm to prepare AEMs with different crosslinking degrees (CEM-X, X = 6,12,18,24,30). 1H NMR and FT-IR showed that PASIm was successfully synthesized and crosslinked with PPO. The prepared membranes had high hydroxide ionic conductivity and excellent alkaline stability. AFM showed that the CEM-18 had obvious microphase separation structure, which was beneficial to the construction of ion channels in the membrane. Thus, the CEM-18 showed the highest ionic conductivity, up to 59.21 mS cm−1 at 80 °C. CEM-24 with higher crosslinking degree showed the highest alkaline stability. After immersing in 1 M KOH solution at 80 °C for 240 h, 86.52% of the initial ionic conductivity was retained. These results indicate that the prepared anion exchange membranes have broad application prospects.

Poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) has been widely studied in the field of anion exchange membranes (AEMs) due to its superior flexibility and chemical stability, but the poor dimensional stability of functionalized SEBS restricts its further application. Thus, we adopt an effective strategy to reinforce AEMs based on SEBS via grafting poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) using Williamson ether synthesis reaction. With
