Capturing the Action: Filming Molecules in the Lab

Studying reactions at the molecular level requires specialized techniques. Imagine filming a volcanic eruption with your phone - it wouldn't work! Special methods are needed to observe these tiny interactions.

The Promise of COFs: Next-Gen Energy Materials

Covalent organic frameworks (COFs) are a promising class of materials with potential applications in battery technology and hydrogen production. However, despite years of research, the details of their formation remained unclear.

Optimizing COF Synthesis From Trial and Error to Precise Control

 COF synthesis involves precise arrangement of molecular building blocks. Understanding why this process works under specific conditions is crucial for optimizing material properties.

A Collaborative Approach: Physics Meets Chemistry

Researchers combined expertise in physics (Cortés and Gruber) and chemistry (Medina) to shed light on the complex synthesis processes of COFs.

Unveiling the Early Stages: Key to Effective COF Design

The initial stages of COF formation, critical for achieving desired functionality, were poorly understood. Visualizing these early reactions was essential.

iSCAT Microscopy: A Powerful Tool for Real-Time Observation

Christoph Gruber used iSCAT microscopy, a technique typically used for studying proteins, to observe COF formation in real-time. This method captures light scattering from tiny particles, revealing their structure and dynamics.

The Unexpected Players: Nano-Droplets and their Crucial Role

The researchers observed the presence of previously unknown nano-droplets in the reaction medium. These tiny structures played a surprising role in controlling the initial stages of COF formation.

Capturing COF Formation in Action: A Movie at the Nanoscale

Using iSCAT, the researchers recorded a film showing the formation of COFs from the very beginning, with a resolution of just a few nanometers. This provided insights into the entire process.

Energy-Efficient Synthesis: A Game-Changer for COF Production

By understanding the role of nano-droplets, the researchers devised a more energy-efficient synthesis process. Simple additions like table salt allowed COF formation at room temperature instead of high temperatures.
