Experimental and Computational Studies of a Multi-Electron Donor–Acceptor Ligand Containing the Thiazolo[5,4-d]thiazole Core and its Incorporation into a Metal–Organic Framework

A ligand containing the thiazolo[5,4-d]thiazole (TzTz) core (acceptor) with terminal triarylamine moieties (donors), N,N′-(thiazolo[5,4-d]thiazole-2,5-diylbis(4,1-phenylene))bis(N-(pyridine-4-yl)pyridin-4-amine (1), was designed as a donor–acceptor system for incorporation into electronically active metal–organic frameworks (MOFs). The capacity for the ligand to undergo multiple sequential oxidation and reduction processes was examined using UV/Vis-near-infrared spectroelectrochemistry (UV/Vis-NIR SEC) in combination with DFT calculations. The delocalized nature of the highest occupied molecular orbital (HOMO) was found to inhibit charge-transfer interactions between the terminal triarylamine moieties upon oxidation, whereas radical species localized on the TzTz core were formed upon reduction. Conversion of 1 to diamagnetic 2+ and 4+ species resulted in marked changes in the emission spectra. Incorporation of this highly delocalized multi-electron donor–acceptor ligand into a new two-dimensional MOF, [Zn(NO3)2(1)] (2), resulted in an inhibition of the oxidation processes, but retention of the reduction capability of 1. Changes in the electrochemistry of 1 upon integration into 2 are broadly consistent with the geometric and electronic constraints enforced by ligation.

It took a while but here’s my latest work including some pretty nice interpenetration isomers!

The metalloligand [Ni(pedt)2]- (pedt = 1-(pyridine-4-yl)ethylene-1,2-dithiolate) has been incorporated into two multi-dimensional structures for the first time. These coordination frameworks represent highly unusual interpenetration isomers and exhibit solid state redox and optical properties that reflect the electronically delocalised nature of the metalloligand.

Chanel Leong’s beautiful work has just been published in Chemical Science!

The presence of donor–acceptor charge transfer in a tetrathiafulvalenenaphthalene diimide-based metal–organic framework (MOF) is investigated using a complementary suite of solid state spectroscopic and electrochemical techniques, and is supported by computational calculations. Solid state electron paramagnetic resonance (EPR) spectroelectrochemistry was employed as a novel method for charge transfer characterization in MOFs.

I am delighted to have been informed today by the international committee from the European Institute of Molecular Magnetism that I have been awarded the


Radicals in Metal Organic Frameworks, a review in RSC Advances written with Dr D’Alessandro

The burgeoning field of metal-organic frameworks (MOFs) has been marked by numerous key advances over the past two decades. An emerging theme is the incorporation of radical species which may be ligated as an integral structural component of, or simply appended to, the material, or else merely a guest within it. Radical incorporation has been shown to endow MOFs with a plethora of unique and fascinating magnetic, electronic and optical properties, paving the way towards their application as spin probes, and in magnetic/electronic devices, chemical sensing and molecular recognition. In view of the rapid growth of literature in the area, this review highlights progress over the past three years (since 2011), and seeks to uncover promising ideas that will underscore future advancements at both the fundamental and applied levels.
