	Prof. Zhang Deqing and colleagues from Institute of Chemistry, Chinese Academy of Sciences have reported a series strategies through modifications of side-chains in organic semiconductors for charge mobility enhancement with the help of 1W1A of Beijing Synchrotron Radiation Facility.

	Prof. Liu Yunqi’ group from the Institute of Chemistry of Chinese Academy of Sciences developed a general two-step approach to obtain electron-withdrawing group (EWG) substituted acceptors based on the BAI unit. The result was published at Advanced Materials (Adv. Funct. Mater. 29, 1804839, 2019).

	Dr. Ge Chen’ team of Institute of Physics Chinese Academy of Sciences designed a high-performance synaptic transistor based on topotactic phase transformation material (SrFeO2.5？SrFeO3) through the O2- ion exchange by ionic liquid gating. This work was published in Advanced Materials (Advanced Materials 31, 1900379, 2019).

	Prof. Wang Tie’ group from the Institute of Chemistry of Chinese Academy of Sciences developed a superficial-layer-enhanced Raman scattering (SLERS) technique for detecting analytes that are noninteractive with Raman-active substrates, by covering elongated tetrahexahedral gold nanoparticle (ETHH Au NP) arrays with a superficial perovskite film.



	Researchers from Key Laboratory of Photochemistry, Institute of Chemistry, Chinese Academy of Sciences investigated the phase transition and thermochromism of copper-based perovskites, with the help of 1W1B-XAFS station at BSRF (Beijing Synchrotron Radiation Facility). They found a lead-free perovskite material (C6H13NH3)2CuCl4 that is thermochromic around 60℃. This work has been published in Science China Chemis...
