1. INTRODUCERE

DEFINITIE-O masina moleculara poate fi definita bl d l l ca un ansamblu de componente moleculare proiectat

pentru a realiza miscari mecanice (output) cand este supusunui stimul extern corespunzator (input)p ( p )

-la ce servesc? -la ce ar putea servi?

-rol bine definit: transmiterea de forte, miscari si energieg

2.ISTORIC

Richard P. Feymann (premiu Nobel in fizica-1965) emite primul ideea construirii masinilor miniaturizate asemanatoare masinilor mecanice construirii masinilor miniaturizate asemanatoare masinilor mecanice

1970-1980- se dezvolta chimia supramolecularaautoasamblareautoorganizare t liautoreplicare

1987-Premiul Nobel in chimie:Donald J. Cram, Jean-Marie Lehn, Charles J. Pedersen

In complex [Ce(21)],rotation around the metal center is slow enough to permit isolation of the two enantiomers by chiral HPLC.
