Chiral Memory in Dynamic Transformation from Porous Organic Cages to Covalent Organic Frameworks for Enantiorecognition Analysis
The preservation of chirality during a transformation
process,
known as the “chiral memory” effect, has garnered significant
attention across multiple research disciplines. Here, we first report
the retention of the original chiral structure during dynamic covalent
chemistry (DCC)-induced structural transformation from porous organic
cages into covalent organic frameworks (COFs). A total of six two-dimensional
chiral COFs constructed by entirely achiral building blocks were obtained
through the DCC-induced substitution of chiral linkers in a homochiral
cage (CC3-R or -S) using achiral
amine monomers. Homochirality of these COFs resulted from the construction
of 3-fold-symmetric benzene-1,3,5-methanimine cores with a propeller-like
configuration of one single-handedness throughout the cage-to-COF
transformation. The obtained chiral COFs can be further utilized as
fluorescence sensors or chiral stationary phases for gas chromatography
with high enantioselectivity. The present study thus highlighted the
great potential to expand the scope of functional chiral materials
via DCC-induced crystal-to-crystal transformation with the chiral
memory effect
