Infrared-Induced Chemistry: From Changes in Molecular Shape to Chemical Reactions and Unusual Crystals
R. Fausto
CQC, Department of Chemistry, University of Coimbra, Portugal

The investigation of infrared-induced chemical is a recent field of research, though its roots may be traced back to the 1963 historical paper by Hall and Pimentel [1], where the relative populations of the two conformers of matrix-isolated nitrous acid could be varied by in situ IR broadband irradiation. Because of lack of efficient selectivity, however, this type of chemistry did not collect, at that time, too much interest among the scientific community. Only 34 years later, the subject gained importance, when high-selectivity in controlling the chemical reactions could be achieved by introduction of narrowband IR excitation [2,3]. Since then, IR-induced chemistry has been developing and, nowadays, it can be used to control the molecular conformation with both high selectivity and efficiency. Furthermore, more recently IR excitation has also been shown to be usable to induce (or facilitate) other types of chemistry [4,5]. the Laboratory for Cryospectroscopy and Biospectroscopy of the University of Coimbra (CQC – Department of Chemistry) has been pioneering this type of investigations, and in this talk I will present a summary of some of our most relevant achievements in the field:

• Efficient control of the molecular conformations by means of narrowband tunable IR excitation, including the generation of rare, elusive conformers otherwise inaccessible to experimentation;
• Application of the research strategy to more complex systems, like dimers;
• Controlling the conformation of selected fragments in a molecule by vibrationally exciting remotely located in space antennas;
• Using vibrational excitation to facilitate tunneling reactions, including processes involving cleavage of chemical bonds;
• Generation of novel high-energy crystals built from high-energy conformers.

Traditionally, a chemist’s task has been to characterize and manipulate atomic and molecular building blocks. On the micron scale, however, we have the opportunity to design altogether new, colloidal, building blocks from the bottom up. This vast synthetic freedom translates into a world of assembly possibilities because while there are a set few atomic units, the colloidal periodic table is seemingly infinite. An enormous research effort is currently taking place to develop heuristics for generating three-dimensional architecture from ”soups” of intelligently designed colloids so that future materials can be imbued with intricate microscale detail.

In this talk, I will present new methods for shaping, programming and assembling matter at the nano- and micron-scale.  A particular emphasis will be given to colloidal fluids of patchy, shape-changing and active particles.
