“…In order to achieve the precise synthesis of optoelectric polymers, the first task is overcoming reaction kinetics and statistics. As shown in Figure , we have developed solid-phase electrosynthesis. − ,, In particular, electrosynthesis accelerates the reaction kinetics at the solid–liquid interface. The similar width of self-assembled molecules and iterative monomers is favored for dynamically allowing the top-down addition during iterative reactions.…”

The synthesis of crystalline polymer with a well‐defined orientated state and a two‐dimensional crystalline size beyond a micrometer will be essential to achieve the highest physical feature of polymer material but remain challenging. Herein, we show the synthesis of the crystalline unipolymer monolayer with an unusual ultrahigh modulus that is higher than the ITO substrate and high conductance by simultaneous electrosynthesis and manipulation. We find that the polymer monolayer has fully extended in the vertical and unidirectional orientation, which is proposed to approach their theoretically highest density, modulus, and conductivity among all aggregation formations of the current polymer. The modulus and current density can reach 40 and 1000 times higher than their amorphous counterpart. It is also found that these monolayers exhibit the bias‐ and length‐dependent multiple charge states and asymmetrically negative differential resistance (NDR) effect, indicating that this unique molecular tailoring and ordering design is promising for multilevel resistive memory devices. Our work demonstrates the creation of a crystalline polymer monolayer for approaching the physical limit of polymer electronic materials and also provides an opportunity to challenge the synthetically iterative limit of an isolated ultra‐long polymer.
