Electric field mediated polymerization...
While the nucleation of two-dimensional polymer domains is not initiated by the applied electric field, their depolymerization and subsequent desorption, are a consequence of the change in the polarity of the substrate bias within the area scanned by the STM tip.
2D covalent organic framework targeting CO2 reduction
A collaborative effort! A rapid method is demonstrated for creating porphyrin-containing single-layered 2D-covalent organic frameworks (s2D-COFs) on a graphite surface. The s2D-COF films, characterized with molecular precision using scanning tunneling microscopy (STM), are used as a cathode for electrochemical CO2 reduction.
Molecular switches on surfaces
Glad to see this collaborative effort on the design and self-assembly of molecular switches on surfaces published.

Published in Nature
We used scanning tunnelling microscopy to follow in real-time, as bonds form and break, molecule by molecule, the birth and growth of 2D dynamic covalent polymers on a solid support immersed in a reactive solution.
Sensing ammonia
We reveal the superior sensing capability of covalently modified graphene layers for ammonia detection
Polymorph detection
We report on the detection and stabilization of a previously unknown two-dimensional (2D) pseudopolymorph.

We demonstrate spatially resolved multicomponent covalent chemical patterning of single layer graphene using a facile and efficient method.
Diazonium Chemistry with a Twist
In this paper, published in Nanoscale, we demonstrate that the ascorbic acid mediated dediazoniation of aryldiazonium salts leads to self-limiting growth of monolayers with high grafting densities
