Abstract

Graphical abstract: A pair of Ce(III) coordination polymers based on chiral semi-rigid T-shaped tricarboxylate enantiomeric ligands are synthesized displaying an interesting 2D structure, the photoluminescent and SHG properties of which are investigated. Abstract: A pair of lanthanide metal chiral coordination polymers (CCPs) based on (R)- and (S)-5-(1-carboxyethoxy) isophthalic acid (H3 CIA), namely, [Ce2 ((R)-CIA)2 (H2 O)5 ]·2H2 O (1-D ) and [Ce2 ((S)-CIA)2 (H2 O)5 ]·2H2 O (1-L ), have been synthesized under solvothermal conditions. Their structures were determined by single crystal X-ray diffraction and further characterized by infrared spectra (IR), powder X-ray diffraction (PXRD), circular dichroism spectra (CD) and thermogravimetric (TG) analyses. CCPs1-D and1-L crystallized in chiral space groups, displaying a 2D chiral 4, 4, 6, 6-c network with a point symbol of (4 10 ·6 5 )(4 6 )2 (4 8 ·6 7 ). Obvious positive or negative cotton effects were found in their CD spectra indicating their homochirality. Moreover, their second harmonic generation efficiency and photoluminescent properties were also investigated.
