Automation Accelerated screening of H-Bond-Rich Iridium Photosensitisers for Hydrogen Generation In the pursuit of a stable hydrogen evolution photosensitiser, we demonstrate the incorporation of a series of our H-bond rich guanidine-styled iridium (III) complexes into a catalytic system. Using automation accelerated catalysis screening techniques we optimised our system quickly and effectively to observe how these strongly H-bonding complexes may perform.

Colour tuneability of heteroleptic iridium complexes through second-sphere coordination† Novel H-bond-rich iridium(III) complexes with different systems of cyclometalating ligands bearing the general formula [Ir(C^N)2(N^N)] were synthesised, characterised and their photophysical properties determined. The incorporated guanidine moieties allow us to introduce a hydrogen-bonding array for the formation of self-assembled iridium-bound hydrogen-bonded systems.

Volume 101 • Number 3 • March 2023 Special issue to honour Professor Suning Wang Introduction Article Vol. 101No. 3pp. 111–117 We have recently reported the synthesis and application of boron–nitrogen dihydroindeno[1,2-b]fluorene derivatives as acceptors in organic photovoltaic devices. Their modest observed efficiencies may be related to the properties of their reduced congeners.
