Cyclic aminomethylphosphines as ligands. Rational design and unpredicted findings.

Rational design of title ligands and their transition metal complexes gave the high effective catalysts for hydrogen economy and perspective "stimuli-responsive" luminescent materials. Together with the above novel cyclic aminomehtylphospine ligands have showed a row of unpredicted properties like spontaneous formation of macrocyclic molecules, unique reversible slitting of macrocycles on to the smaller cycles, rapid interconversion of the isomers catalyzed by both acids and transitional metals, bridging behavior of usually chelating ligands and unexpected high influence of handling substituents on N-atoms on to the catalytic and luminescent properties of P-complexes.
