N,O-Type Carborane-Based Materials

Abstract

This review summarizes the synthesis and coordination chemistry of a series of carboranyl ligands containing N,O donors. Such carborane-based ligands are scarcely reported in the literature when compared to other heteroatom-containing donors. The synthetic routes for metal complexes of these N,O-type carborane ligands are summarized and the properties of such complexes are described in detail. Particular attention is paid to the effect that the incorporation of carboranes has into the coordination chemistry of the otherwise carbon-based ligands and the properties of such materials. The reported complexes show a variety of properties such as those used in magnetic, chiroptical, nonlinear optical, catalytic and biomedical applications.

Carborane Bis-pyridylalcohols as Linkers for Coordination Polymers: Synthesis, Crystal Structures, and Guest-Framework Dependent Mechanical Properties

“…In addition to that, the high thermal and chemical stability, acceptor character and 3D nature of the icosahedral carborane clusters make them valuable ligands in coordination chemistry. [18][19][20][21][22][23] For example, Mirkin and co-workers explored the use of di-, tri-and tetra-carboxylic acid derivatives of para-carborane (I to IV in Scheme 1) for CP synthesis, providing a series of CPs exhibiting unprecedented stabilities with respect to thermal degradation, inherited from the carborane moiety. [24][25][26][27][28][29][30] Some of the CPs including these polycarboxylato p-carborane-based linkers showed gas uptake properties and excellent selectivity for CO 2 /CH 4 mixtures.…”

Boron-Based (Nano-)Materials: Fundamentals and Applications

“…The present special issue is an important scientific contribution to the field of boron science, and we, the contributors, have all been actors of this successful publication. "New developments are appearing constantly and are limited only by our imagination" [15].…”

“…The first is proposed by Planas et al [15]. The review summarizes the synthetic routes, coordination chemistry, and properties of a series of carboranyl ligands containing N, O donors (e.g., closo-carbonylmethylalcohols with nitrogenated aromatic rings) as well as of metal (e.g., cobalt, iron, platinum, titanium) complexes of these N,O-type carborane ligands.…”

Rational design of carborane-based Cu2-paddle wheel coordination polymers for increased hydrolytic stability

“…[39][40][41][42] In pursuit of synthesizing water-resistant MOFs, we are working on the design and preparation of carborane based ligands. [43][44][45][46][47][48] Incorporation of such ligands into CPs or MOFs is known to increase their thermal [49][50][51][52][53][54][55][56] and hydrolytic-stability. 27,[57][58][59][60] For example, we have recently reported the most stable Cu-paddle wheel MOF in the literature against water.…”
