摘要：

Herein, we discovered that the surface-confined condensation of boronic acid can happen spontaneously at room temperature, by comparing the kinetics of condensation of boronic acids with and without the negative sample bias, we found that the negative sample bias indeed accelerates the self-condensation reaction of boronic acid. Combining with in-situ STM images and ultraviolet photoemission spectrum (UPS) analysis, a reversible adsorption mechanism model was proposed and reasonably explains the reversible electric-field-induced phase transformation. & COPY; 2023 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
