Chemists from have created a new material that assembles predictably and reproducibly into 2-D networks. The material has a number of new features, which means that it can have many applications. However, it will take time and extensive research to determine how best to use it.

Importantly, research provides a very rare example of bottom-up material production. It is extremely difficult to control a self-organizing material so that chemists can reliably predict and reproduce its structure, depending on the environment in which it is located ̵

1; but the Trinity team has done just that.

In addition, scientists have long been interested in developing self-assembly with anion templates, as they have great potential for removing dangerous and environmentally harmful molecules from the environment. However, working with anions (negative charge ions) instead of cations (positive charge ions) is molecularly difficult for several reasons.

Thorfinnur Gunnlaugsson, Professor of Chemistry at Trinity, said:

"Anions are widespread in our world, many of them having specific roles in nature – both living and inanimate matter However, often mediated by specificity, changes in these interactions result. For this reason, we have always wanted to understand how these molecules combine to mimic the interaction of proteins and enzymes with anions in nature.

It is Unbelievably challenging to create a material that does exactly what you think – and what you need – in different environments, as environments are rarely always stable to a dark art, but after a lot of work, we've successfully created something that's controlled "hierarchical 2-D network, and we can predict exactly what it will look like in different environments."

Her groundbreaking work was supported by the Science Foundation Ireland and involved working with researchers at the MacDiarmid Institute for Advanced Materials and Nanotechnology at the University of Canterbury. It is described in the internationally recognized journal Chem .

The team is now excited to investigate the properties of the new material in order to consider potential applications around the world. It is possible that it has an impact on health through targeted drug delivery (it is biocompatible). when printing or in an environment where gels are used; or even in the world of electronics, where new materials are touted as the key to long lasting batteries and improved performance of high quality goods.

Professor Mick Morris, director of the SFI AMBER Research Center in Trinity, added:

"The potential of this work can not be underestimated." It is the work of many years and the collaborator in the laboratory of Professor Gunnlaugsson, using chemical methods too Designing to synthesize complex materials through design – and thus enabling their application in many areas – is an important part of our AMBER program so that the Center can meet challenges we may have thought impossible.
