 Research activity are related to sustainable chemistry and protection of the environment is an integral part of one of the principal axes in LCH (UMR CNRS 5182) program.

The studies are focused on the chemistry of nitrogen ligands and their complexes and consist of three main topics:

·      development of chemosensors and sensing materials for selective detection of harmful and environmentally-relevant metal ions;

·      biomimetic  studies  of  supramolecular  metal  complexes  and  coordination  polymers, aiming  at  a  deeper  comprehension  of  natural  processes  and  development  of  advanced photoactive and thermochromic materials;

·      preparation of porous organic-inorganic materials for sustainable catalytic reactions.

Our  “bottom up”  strategy  is composed  of  three  consecutive  steps:  1) synthesis of sophisticated  nitrogen  ligands  functionalized  by  phosphonate and carboxylate groups; 2) investigation   of   their  coordination   properties;  3)  design  and preparation of  functional organic-inorganic   materials. We   are   developing   rational   synthetic   approaches   to functionalized   nitrogen   ligands,   studying   their   unusual   coordination    properties and exploring different routes for their immobilization such as self-assembly, incorporation into crystalline metal-organic frameworks and amorphous metal oxide matrices, grafting onto a surface of metal oxides and preparation of film materials by using SAM and LB techniques.

            In 2011-2019 we collaborated with six Russian groups (Pr. V. Arslanov, Dr. A. Averin, Pr. I. Beletskaya, Dr. A. Cheprakov, Dr. Yu. Gorbunova, Pr. S. Nefedov) in the frames of International Associated Laboratory of CNRS «LAboratory of Macrocyclic systems and RElated Materials» (LAMREM) and Pr. K. Kadish group (Houston University).
