Keen desires for artificial mimicry of biological polymers and property improvement synthesized ones have triggered intensive explorations sequence-controlled copolymerization. However, conventional synthesis faces great challenges to achieve this goal due the strict requirements on reaction kinetics comonomer pairs tedious synthetic processes. Here, alternating copolymerization with molecular precision is realized surface. The stoichiometric control serves as a thermodynamic strategy steer...
Preparing chiral polymers by using achiral building blocks in an reaction environment is very demanding because this strategy avoids the use of expensive reagents. Here, a surface-confined and sequence-controlled copolymer synthesized organometallic reactions between precursors 4,4″-dibromo-1,1′:3′,1′′-terphenyl 1-ethynyl-4-[2-(4-ethynylphenyl)ethynyl]benzene on Ag(111) surface. Combined scanning tunneling microscopy density functional theory explorations show that terminal alkyne aromatic...
An apparatus for explorations of ion transport in a medium and across an interface has been constructed. The soft-landing technique is used to deposit low-energy ions onto pre-adsorbed layer on metal substrate. designed source can produce mass-filtered beam with tens nanoampere from solid sources such as bulk metals salts. kinetic energy the be lower than 1.0 eV, enabling soft-landed at surface. A Kelvin probe resolution less 32 mV incorporated measure surface potential (SP) variation...
