Area of Science:

• Materials Science
• Polymer Chemistry
• Electrochemistry

Background:

• Organometallic polymers are promising for high-density data storage and anti-counterfeiting due to stimuli-responsive properties.
• Controllable synthesis of these polymers with defined sequences remains a significant challenge in materials science.

Purpose of the Study:

• To demonstrate the feasibility of precise monomer insertion for creating complex polymer architectures.

Main Methods:

• Rapid sequence-controlled electrosynthesis utilizing oxidative and reductive C-C couplings.
• 1-minute reaction times for monomer insertion, avoiding protecting/deprotecting steps.
• Monitoring synthesis progress using UV-vis spectra and cyclic voltammetry.

Main Results:

• Achieved single-monomer-precision propagation in organometallic polymer synthesis.
• Demonstrated uniform synthesis and sequence control.
• Successfully incorporated diverse metal and ligand species into complex polymer structures.

Conclusions:

• Electrosynthesis offers an efficient and potentially automated route to sequence-defined organometallic polymers.
