Polyaniline (PANI) has been studied as soft electronic materials, which is still subject to performance obstacles such as low thermal conductivity and undesirable electrical conductivity. Herein, we report the in situ preparation of an atomically thin hydroxylated boron nitride (HO-BNNS)@PANI actiniae-like layered composite. HO-BNNS@PANI composite obtains brilliant electrical and thermal conductivity without destroying the pH sensitivity of PANI. In this case, the test results show that when the HO-BNNS content is 15 wt%, the conductivity of the HO-BNNS@PANI composite is 10.8 S cm −1 , and the thermal conductivity is 1.21 W m −1 •K −1 (≈520% that of pure PANI). More strikingly, the HO-BNNS@PANI composite maintains the pH responsiveness of the intrinsic PANI. This greatly improves the application range of composite materials. Meanwhile, since actiniae-like structural factors simultaneously improve ion diffusion capability and optimize reaction area, after five times of doping and dedoping, the conductivity of the HO-BNNS@PANI composite can still be maintained above 60%.

Based on the concept of green lifestyle, we propose to design an electric scooter that can adapt to modern traffic conditions, increase the willingness of the general public to travel green and solve the last mile problem. Focusing on the design of electric scooters under the concept of green lifestyle, research and analysis of the needs of electric scooter users by means of a questionnaire designed with the KANO model, and the design categories and elements of electric scooters were derived, combined with the BEV-E lifestyle model and IDR lifestyle design method to analyze and propose the design strategy of electric scooters, on the basis of which the optimal design practice of electric scooters was carried out. Finally, the electric scooter is constructed so that the electric scooter can meet people's green travel needs while planning and designing the lifestyle of the consumer as a whole, guiding people towards a green lifestyle and expanding the extension direction of the sustainable design concept.

A Pd‐catalyzed coupling reaction from o‐alkynylanilines and o‐(2,2‐dibromovinyl)anilines for the synthesis of 2,3′‐bisindoles is developed. In which, o‐ethynylaniline was used as 3‐functionalized indole precursor and o‐(2,2‐dibromovinyl)aniline was used as 2‐functionalized indole precursor. This protocol exhibits high efficiency, good functional group tolerance and scalability from easily accessible starting materials.
