The main focus is to transform polymers into smart materials, to meet the rising demand of safety-related, non-destructive tests in structural composites. Molecular recognition has been chosen as an operating tool in the form of supramolecular cross-linking among complementary host-guest units embedded in the polymeric chains. The guests are selected luminophores, which are quenched in the complex and emitting in the free form. The hosts are calixarenes, cavitands and cucurbiturils, whose molecular recognition properties are well defined and predictable. The experimental part of the project includes: Micro-scale crystallization of the supramolecular polymers and their selected models; structural characterization by X-ray diffraction data from single crystal or powder will be used to obtain the 3D arrangement; small-angle X-ray scattering (SAXS) and Wide-angle X-ray scattering (WAXS) measurements using synchrotron radiation will also be performed to measure the electrospun nanofibers.
