| 2 | Two-dimensional molecular crystalline semiconductors towards advanced organic optoelectronics显示文摘The compelling demand for higher performance and lower cost in the optoelectronics industry has driven the development of organic semiconductors.Molecular crystalline semiconductors(MCSs),especially two-dimensional MCSs(2D-MCSs),possess intrinsic ordered structure,quantum confinement effect,high mobility,unique optical and electrical properties,and more ecological and cheaper production,which make great promises in high-performance optoelectronic applications.Here we provide a review of design principles and synthetic strategies for 2D-MCS materials,exploiting their potential as a revolution option in associated optoelectronic devices.The merits and limitations of each strategy are presented,and these molecular crystals are considered as a competitive choice for emerging semiconducting materials in information science.Finally,the current challenges and future perspectives in this field are also elaborated. | Xuemei Dong Heshan Zhang Yinxiang Li Bin Liu Keyuan Pan Yijie Nie Mengna Yu Mustafa Eginligil Juqing Liu Wei Huang | 2022 | Nano Research2022，15，10： | 0 |
| 3 | Oxidative thiocyanation of allylic alcohols:an easy access to allylic thiocyanates with K_(2)S_(2)O_(8) and NH_(4)SCN显示文摘A practical method for the synthesis of allylic thioacyanates from allylic alcohols was disclosed employing K_(2)S_(2)O_(8) as the oxidant and NH_(4)SCN as the thiocyanate source.Without introducing a leaving group in advance,a series of disubstituted and monosubstituted allylic thiocyanate compounds were obtained in moderate to good yields.This transition metal-free method features mild reaction conditions,broad sub-strate scope and operational simplicity.The potential application of this method was demonstrated by some derivatization reactions of the product and mechanistic investigation indicated that a radical process is involved. | Keyuan Zhang Tianbing Liang Yulong Wang Chonglong He Mingyou Hu Xin-Hua Duan Le Liu | 2022 | Organic Chemistry Frontiers2022，9，4： | 0 |
| 4 | Two New Species of Fire-Bellied Newts (Caudata, Salamandridae, Cynops) from Southeastern China显示文摘The fire-bellied newt genus Cynops contains ten known species distributed in China and Japan in East Asia.In this work,two new Cynops species are described,namely Cynops jiaoren sp.nov.distributed in northern Guangdong and Cynops maguae sp.nov.distributed in eastern Jiangxi.The two new species can be distinctly distinguished from their congeners by the independent phylogenetic placements and a combination of morphological characteristics.The discovery of these two new species in the Southeast Chinese Hilly Area,where half of congeners occur,increases the known diversity of Cynops,and indicates unresolved relationships among the species in southeastern China.Further discussions on the taxonomic status of Cynops cyanurus are also provided. | Zhitong LYU Shuo QI Siyu ZHANG Keyuan DAI Yingyong WANG | 2023 | Asian Herpetological Research2023，14，1： | 0 |
