Highly Stable Non-Hysteretic {Cu2(tebpz) MOF + Water} Molecular Spring.
Résumé
A molecular spring formed by a hydrophobic metal–organic framework Cu2(tebpz) (tebpz=3,3′,5,5′-tetraethyl-4,4′-bipyrazolate) and water is presented. This nanoporous heterogeneous lyophobic system (HLS) has exceptional properties compared to numerous reported systems of such type in terms of stability, efficiency, and operating pressure. Mechanical and thermal energetic characteristics as well as stability of the system are discussed and compared in detail with those of other previously reported HLS.
