Sam, Anna and Dermot teach TY students about molecular logic

As part of the School of Chemisty’s annual Transition Year (TY) programme, Sam, Anna and Dermot gave an interactive demonstration on molecular logic to a group of sixty TY students. This is the second year in a row that the group has presented on smart materials and chemical computation, in an informative lecture that covers the life and legacy of mathematician George Boole, logic gates and the life-saving work of Prof A.P. de Silva in Belfast, and our own group’s work with lanthanides.

The students learned how logical functions operate in a series of interactive exercises, before testing out the gel-based logic gates themselves. The demonstration was originally developed by Sam and Joe as part of Discover Research Dublin 2015, and to mark the 200th birthday of Boole.

“Luminescent Logic in Soft Materials” presentation wins prize at Discover Research Dublin open night

Recent research from the TG Group on the use of lanthanide luminescent soft materials as molecular logic gate mimics was presented to the public as part of the Discover Dublin Research Night in the Trinity Biomedical Sciences Institute on 25th September 2015. The work was described in an RTÉ News bulletin the day before and many people attended the laboratory where Sam Bradberry, Joe Byrne and Anna Aletti showed them how research chemists can create functional materials from commercially available building blocks, step by step. Illustrations by artist Sophie Longwill helped communicate the complex ideas to an audience of all ages. The presentation won a prize as a result of feedback from visitors.

The research was recently published in an article in Chemical Communications. It describes the use of lanthanide luminescent bundles based on the “Trinity Sliotar” and the btp motif as components in methacrylate-based soft materials and their use as responsive functional materials, and with luminescent outputs which can be described in terms of logic gates.
