Multi-functional magnetic, ferroelectric, and fluorescent homochiral lanthanide (Ln)–camphorate compounds built on helical {Ln–O}n inorganic substructures

Abstract

The design and preparation of homochiral metal–organic coordination polymers is presently a topic of intense focus. Herein, we present a series of isomorphous Ln(III)–camphorate compounds with the P6₅ chiral space group. The overall structural feature is the hex rod-packing architecture, where each helical {Ln–O}_n inorganic substructure connects to six analogs via chiral D-cam spacers (D-H₂Cam = D-camphoric acid). Moreover, the Ln-related magnetic, fluorescent and chirality-related ferroelectric merits of these compounds are explored.
