The collaboration between the research groups of professors Pau Ballester and Jose R. Galan-Mascaros at the Institute of Chemical Research of Catalonia (ICIQ), Dr. Jonas Bjork at Linkoping University and the group of Dr. David Ecija at Institute IMDEA Nanoscience has allowed the development of a new chemical reaction for the synthesis of low-dimensional polymers that can be rationalised as phthalocyanine derivatives.

The results obtained have been published in Nature Communications.

Surface-mediated synthesis of low-dimensional polymers from simple molecular precursors is a rapidly emerging field. In this work, the researchers introduce surface-confined thermally tunable reaction pathways as a route to select intramolecular versus intermolecular reactions yielding either monomeric phthalocyanines or low-dimensional phthalocyanine polymers, respectively.The precursor was designed and synthesised at ICIQ's laboratories.

Next at IMDEA Nanoscience, it was deposited on a gold surface where it has been gently annealed to more than 300C in order to study its behaviour.

When the temperature rises up to 275C, the polymerisation of the molecule occurs resulting in phthalocyanine unidimensional polymers (phthalocyanine tapes) that had not been synthesised so far. However, if the molecules are deposited on a substrate held at 300C, the polymeric growth is blocked and the precursor is transformed into individual phthalocyanines.

This selectivity induced by temperature, despite being a promising strategy for increasing the synthetic versatility, had not been used on surfaces up to now. Nevertheless, this use could have huge advantages when engineering nanostructures with technological applications.

"On-surface synthesis is a promising strategy for the formation of nanostructures. This new thermally controlled reaction presents a very interesting alternative for the development of new polymeric materials, which will satisfy the growing demand from disciplines such as nanotechnology, information technology and biotechnology" -say Prof. Galan-Mascaros and Dr. David Ecija.

Osaka, Japan (SPX) Jul 13, 2016
A research team in Japan has now succeeded in developing high precision X-ray deformable mirrors that can be configured as necessary. They are the first to have achieved the formation of three types of X-ray focused beams, which differ in focused spot size, without changing the experimental setup. These findings constitute a considerable step towards developing a multifunctional X-ray microscope ... read more
