## Description

- description: The asymmetric introduction of functional groups into polymers is promising
    due to its potential to provide novel electronic and magnetic properties. Though
    traditional on-surface bottom-up synthesis has succeeded in creating various types
    of polymers, it struggles at realizing asymmetry due to the difficulty of stereoregular
    polymerization and the tendency for overall polarity cancellation during agglomeration.
    Here, enabled by the low halogen-contaminated metal surfaces provided by two-zone
    chemical vapor deposition, “compass” precursors possessing three independent bonding,
    edge, and dipole vectors undergo isotactic polymerization via the vectorial self-assembly
    of chiral precursor diradicals without the need for chiral catalysts required
    in conventional in-solution polymerization. The isotactic polymers exhibit polar
    2D crystalline structures due to the hetero-edge CH–π interaction between the
    standing phenyl and butoxy group surpassing the homo-edge interactions of π–π
    and CHCH. The developed vectorial on-surface synthetic technique not only paves
    the way to the realization of stereoregular control but also unlocks unprecedented
    crystal engineering.
