Polymer Research Group

The Polymer group was founded by Judith Percino Z. PhD. and Victor Manuel Chapela Castañares PhD. in 1993.

The Polymers group’s research addresses fundamental problems in physical chemistry of materials, as is the property-structure relationship. Research is conducted on experimental and theoretical calculations of unconventional materials with low and high molecular weight in order to relate to their physical-chemical properties, to obtain feedback on the design of new compounds and bring them level synthesis and so improve the physical-chemical properties. Among those properties studied are phenomena such as photochromism, fluorescence, the polyelectrolyte effect, and conductivity.

Current issues related to changes in the molecular structure of materials, and key answering questions about everyday phenomena which are not entirely understood, are addressed. For example, ¿why is it that some materials exhibit fluorescence only as liquids?, ¿why not in solid state?, or why only in solid state? Or more so, ¿what makes materials have higher quantum efficiency? The synthesis of low molecular weight compounds functionalized to achieve polymers is carried out, which can be useful as electro-optical sensors, among other applications.

Research Interest

Relevant Topics

Research is mainly carried out on the synthesis of novel monomers and polymerization processes, thus condensation, via free radicals and currently CRP, which are important for controlled processes.

The group probe the states of aggregation of colloidal particles in the presence of polyelectrolytes and multivalent ions. It is accompanied by experimental tools such as dilatometry, IR, NMR, Mass, including light scattering.

It synthesizes novel compounds (including polymers) with predetermined chemical structures, especially type o-, p- arsanilic, styrilpyridines, Schiff bases, phenylvynilidene, in order to study the optoelectronic properties (e.g. fluorescence quantum yield) for applications in OLEDs, biosensors, etc.

The conjugates are from the point of view of experimental-computational calculations, for which students must obtain experimental results and correlate with the results of theoretical calculations systems. This synergy allows us to elucidate structure-property trends leading to prediction of the physicochemical behavior of newly conjugated systems and thereby, prediction of the most appropriate tech - application.

Our research group is also interested in acrylonitriles derivatives, analyzing their physicochemical properties and supramolecular architectures using X-ray diffraction and the DFT method. In brief, Hirshfeld surfaces and 2D finger print plots are constructed to identify the differences in-between intermolecular interactions and contacts from different crystal structures. The lattice energies of the crystal structures are calculated using the PIXEL method and the energetics of various intermolecular interactions, present in different molecular pair, are quantified.
