    A tetraphenylethylene core-based small molecular acceptor with a unique 3D molecular structure is developed. Bulk-hetero­jucntion blend films with a small feature size (≈20 nm) are obtained, which lead to non-fullerene organic solar cells (OSCs) with 5.5% power conversion efficiency. The work provides a new molecular design approach to efficient non-fullerene OSCs based on 3D-structured small-molecule acceptors.

    A high molecular weight donor–acceptor conjugated polymer is synthesized using Suzuki polycondensation method. Using this polymer, a single junction bulk heterojunction solar cell is fabricated giving a power conversion efficiency of 9.4% using a fullerene-modified ZnO interlayer at the cathode contact.

    Biomaterials are successfully integrated in OTFT devices as biorecognition elements to develop ultrasensitive label-free electronic biosensors or as gating materials to obtain highly performing devices.

  4. Active Micro-Actuators for Optical Modulation Based on a Planar Sliding Triboelectric Nanogenerator

    Based on a triboelectric nanogenerator (TENG) the first active micro-actuator for optical modulation driven by mechanical energy without external power or mechanical joint is presented. This demonstrates the enormous potential of TENGs for independent and sustainable self-powered micro/nano electromechanical systems, and opens up new ­applications of TENGs in triboelectric-voltage-controlled devices.

  5. Superelastic Supercapacitors with High Performances during Stretching

    A fiber-shaped supercapacitor that can be stretched over 400% is developed by using two aligned carbon nanotube/polyaniline composite sheets as electrodes. A high specific capacitance of approximately 79.4 F g−1 is well maintained after stretching at a strain of 300% for 5000 cycles or 100.8 F g−1 after bending for 5000 cycles at a current density of 1 A g−1. In particular, the high specific capacitance is maintained by 95.8% at a stretching speed as high as 30 mm s−1.
