Various members of the TG Group were involved in the meeting on Photochemistry and Photochemical effects organised by the RSC Photochemical Group with Dublin Chemistry and incorporating the Young and Early Career Researchers’ Meeting 2011. Despite the visit of Queen Elizabeth II to Trinity College, the meeting went ahead in UCD on Monday and Tuesday, before returning to the intended venue for the final day. Dr Steve Comby gave a talk on sensing of biologically relevant d-metal ions using lanthanides cyclen-based luminescent displacement assays in aqueous solution. Robert Elmes spoke the next day about his work on ruthenium (II) polypyridyl complexes as potential DNA probes and anti-cancer phototherapetics. Posters were presented by Swagata Banerjee, Dawn Barry, Jon Kitchen, and Robert Elmes. The meeting was a great success thanks to organisers Rachel Evans, John Kelly and Han Vos.
