represent
some of the most fascinating phenomena in chemistry. They are not
only intriguing from a basic science point of view but also provide
a means to modify or tune the properties of the materials via the
postsynthetic introduction of suitable guest molecules or organic
functional groups into their structures. Here, we describe UCY-2, a new flexible Nd3+ metal–organic framework (MOF),
which exhibits a unique capability to undergo a plethora of SCSC transformations
with some of them being very uncommon. These structural alterations
involve the replacement of coordinating solvent molecules of UCY-2 by terminally ligating solvents and organic ligands
with multiple functional groups including −OH, −SH,
−NH–, and −NH2 or their combinations,
chelating ligands, anions, and two different organic compounds. The
SCSC coordinating solvent exchange is thus demonstrated as a powerful
method for the functionalization of MOFs.
