Modular Solutions for the New Multicomponent Molecular Systems

This NCN project „Rozwiązania modularne dla nowych wieloskładnikowych materiałów molekularnych" (English title: „Modular Solutions for the New Multicomponent Molecular Systems” (UMO-2019/35/B/ST5/01481 OPUS 18) is performed under the supervision of dr Robert Podgajny (associate professor UJ) in the ZNMM Group (Inorganic Molecular Materials Group) at the Faculty of Chemistry, Jagiellonian University in Krakow (UJ).

SUMMARY OF THE PROJECT

The project is devoted to the modular design and construction of multi-component molecular materials that provide the perspective of switchable materials exploiting structural, magnetic and optical properties. The strategy is based on the use of the substrates able to provide block-like 1-D or 2-D synthons via the addressing of particular areas on the molecular surface or sites in the crystal lattice. The project aims towards the discrete and polymeric multicomponent systems based on specific ions or ions’ combinations as well as on the organic components of specific distribution of functional groups and electrostatic potential, exploiting recognized structural and electronic matching. It is planned to achieve (1) new multisite anions receptors based on the cooperative charge-transfer anion-π interactions, (2) new systems with interesting optical properties (absorption, luminescence) tuned by the molecular aggregation, (3) new crystalline composites based on the epitaxial growth of the isostructural crystal lattices revealing different functional properties (SCSC, ET, SCO) and (4) new functional coordination systems involving the organic components of non-typical molecular structure, valence electronic structure and distribution of functional groups, electronic density, electrostatic surface potential and quadrupole moment.

Duration time: July 2020 – June 2024 (48 months).

Budget: 1 923 132 zł.

The project team has a direct access to the following equipment:

• gloveboxes, vacuum lines and solvent purification station;

• equipment dedicated to the solvothermal syntheses;

• MPMS-3 SQUID magnetometer (equipped with the pressure cell and light irradiation option);

• Bruker D8 Quest Eco single crystal diffractometer equipped with the new generation CPAD PHOTON II C14 detector (this part was purchased from the project sources);

• powder diffractometers (D8 Advance Eco, Bruker);

• basic analytical facilities: elemental CHNS analysis, TGA/QMS, DSC, FT IR microscope;

• modern UV-3600i Plus UV-Vis-NIR spectrophotometer accommodated to the solution and solid state measurements under various temperatures, vacuum conditions and light irradiation (Praying Mantis) (this part was purchased from the project sources);

• luminescence spectrometer UV-Vis-NIR (FS-5, Edinburgh Instruments) equipped with the thermal measurements setup;

• dynamic vapor sorption SMS DVS Resolution apparatus.

The project team has also the access to other magnetometers, PPMS set up, 57Fe Moessbauer, 1H and 13C NMR, mass, and EPR spectrometers, and SEM EDS facility in the associated groups in Kraków. The cooperation could be also appointed for the DFT or ab-initio theoretical description of the most interesting systems.

The accepted candidates will be provided with the access to the literature sources (periodics, databases), and could count on the support from the members of the ZNMM group.
