| 1 | High-speed flexible near-infrared organic photodiode for optical communication显示文摘Optical communication is a particularly compelling technology for tackling the speed and capacity bottlenecks in data communication in modern society.Currently,the silicon photodetector plays a dominant role in high-speed optical communication across the visible-near-infrared spectrum.However,its intrinsic rigid structure,high working bias and low responsivity essentially limit its application in next-generation flexible optoelectronic devices.Herein,we report a narrow-bandgap non-fullerene acceptor(NFA)with a remarkableπ-extension in the direction of both central and end units(CH17)with respect to the Y6 series,which demonstrates a more effective and compact 3D molecular packing,leading to lower trap states and energetic disorders in the photoactive film.Consequently,the optimized solution-processed organic photodetector(OPD)with CH17 exhibits a remarkable response time of 91 ns(λ=880 nm)due to the high charge mobility and low parasitic capacitance,exceeding the values of most commercial Si photodiodes and all NFA-based OPDs operating in self-powered mode.More significantly,the flexible OPD exhibits negligible performance attenuation(<1%)after bending for 500 cycles,and maintains 96% of its initial performance even after 550 h of indoor exposure.Furthermore,the high-speed OPD demonstrates a high data transmission rate of 80 MHz with a bit error rate of 3.5×10^(-4),meaning it has great potential in next-generation high-speed flexible optical communication systems. | Yu Zhu Hongbin Chen Ruiman Han Hao Qin Zhaoyang Yao Hang Liu Yanfeng Ma Xiangjian Wan Guanghui Li Yongsheng Chen | 2024 | National Science Review2024，11，3： | 0 |
