# Nanoporous BNC network on Au(111) from a borazine-based arylalkyne

## TL;DR

A new method creates nanoporous boron-nitrogen-carbon networks on gold surfaces using a borazine-based compound.

## Contribution

A borazine-based arylalkyne forms BN-doped nanoporous networks on Au(111) through cyclotrimerisation.

## Key findings

- Thermally induced cyclotrimerisation forms regular BN-doped patterns on Au(111).
- Borazine cores remain intact during the reaction, confirmed by STM and XPS.
- Nanoporous BNC networks are successfully synthesized using this method.

## Abstract

On Au(111), an alkyne-terminated borazine derivative undergoes thermally induced cyclotrimerisation, forming nanoporous boron-nitrogen-carbon networks featuring regular BN-doped patterns, with borazine cores preserved during the reaction as characterised by scanning tunnelling microscopy (STM) and X-ray photoelectron spectroscopy (XPS).
