Polymer Defect Engineering – Conductive 2D Organic Platelets from Precise Thiophene-Doped Polyethylene

Authors: Max Planck Institute for Polymer Research, Germany; University of Twente, Netherlands

Abstract

We developed a simple way to create 2D conductive nanostructures with dielectric cores and conductive surfaces based on polyethylene with in-chain thiophene groups. Generally, thiophene-based polymers show great conductive properties, but exhibit a poor processability. Here, we use the crystallization of a polyethylene chain with precisely distributed thiophene groups as the platform for a self-organization of a lamellar structure. During crystallization, thiophene groups are expelled to the crystal surface. Subsequent copolymerization with 3,4-ethylenedioxythiophene (EDOT) molecules finally yields 2D platelets with a conductive surface. The electric properties of the surface are demonstrated by conductivity measurements. Given the molecular structure of the polymer, it can be assumed that the conductive layer consists of only one monoatomic layer of polymerized thiophene. We thus show a new way to create an ultra-thin, conductive surface on a polymer surface in just a few steps. Hence, the method presented here opens up a wide range of possibilities to produce complex, nanoscale electronic structures for microelectronic applications.

Rappsilber Laboratory, Insitute of Biotechnology, Technical University Berlin, Germany

Q: WHAT IS THE FOCUS OF YOUR LAB’S RESEARCH?

A: The Rappsilber Laboratory is interested in studying the machinery of life, in particular protein structures and their interactions in living cells. Determining protein behaviour is crucial for developing new drugs or understanding terrible diseases such as cancer. We are doing this by developing state-of-the-art methods and new chemical tools for crosslinking mass spectrometry (crosslinking-MS), including new crosslinker reagents and crosslinking chemistry. Working on the chemistry-biology interface, our work encompasses chemical synthesis of peptides, fluorophore tagged sensors, peptide- and protein-reactive crosslinking reagents and bioorthogonal metal catalysts.

Q: WHAT WAS YOUR PREVIOUS WORKFLOW OR CHALLENGES?

A: This year (2020) we built a chemistry lab from scratch, here at the Institute of Biotechnology (TU Berlin). We had the opportunity to really think about our work flow requirements and create the most efficient chemical synthesis pipeline for a modern, 21st century, small chemistry laboratory. However, we are a satellite campus, located more than 10 km from the Institute of Chemistry, which meant that we were constrained by the lack of usual chemistry infrastructure. One of the major challenges that we faced here, is that without chemistry-specific analytical capability, we are working almost blind. Every step of chemical synthesis, including reaction monitoring, work-up, purification and final product characterisation required an exhausting and disruptive journey across Berlin!

Q: WHY DID YOU INCORPORATE THE EXPRESSION® CMS INTO YOUR LABORATORY?

A: We operate an advanced proteomics facility, with cutting edge, high-precision, high sensitivity mass spectrometers for analysing extremely complex peptide mixtures. But a chemist needs a workhorse, not a Formula 1 car. The Advion Interchim Scientific expression® CMS was a no-brainer. We needed a system that is versatile, compact, easy-to-use, easy-to-maintain (~10 minute calibration), robust and allows fast analysis (result in <30 seconds). This system is all of this, but furthermore it is a delight to use. The ASAP® Direct Analysis Probe works fantastically well for analysis of solids and liquids. Switching between APCI and ESI is so quick and easy. The Plate Express® system makes it a joy to identify reaction products directly from TLC plates, greatly simplifying subsequent purifications. The Plate Express™ also works really well for identifying synthesized peptides from TLC spots. The expression® CMS sits at the heart of our chemistry lab and workflow.

Q: WHO WOULD YOU RECOMMEND TO PURCHASE THE EXPRESSION® CMS?

A: We would recommend the Advion Interchim Scientific expression® CMS to literally any research laboratory, big or small. The versatility of the system is truly impressive.

Breaking Through Bottlenecks in Organic Synthesis with a Streamlined Purification Workflow

Successfully completing an organic synthesis involves three typically lengthy, but crucial steps: reaction monitoring, compound identification, and purification. These steps can create bottlenecks in the synthesis, unless a purpose-built, streamlined, and reliable workflow is on hand.
This whitepaper delves into some of the challenges faced by synthetic organic chemists as they navigate compound identification and purification struggles. It also describes how using a workflow that couples thin layer chromatography (TLC) and mass spectrometry (MS) to flash purification can help increase the efficiency of the entire process.

Key Objectives:

  • Understand how a workflow that combines thin-layer chromatography, mass spectrometry, and flash purification can increase the speed and efficiency of an entire organic synthesis process.
  • Learn about prep-free techniques that have become the new standard: scraping TLC spots, developing flash methods and performing long liquid chromatography/MS runs are not necessary with modern instrumentation that is specifically developed to take the prep-work and guess-work out of the purification process.
  • Become informed about a cost-effective, user-friendly benchtop workflow solution for organic compound identification and purification that can save time and money for any lab.
