Due to the impending end of Moore's Law, new materials are being explored to replace silicon as the basis of electronics. Photochemical molecular switches such as spiropyrans are candidates to be used in "molecular electronics ". In this work a series of mono- and dialkynyl spiropyrans were synthesised, to which ruthenium moieties and gold-binding groups were attached. The addition of a ruthenium centre to one spiropyran increased the stability of its photogenerated form by a factor of 22. Measurement of the difference in conductivity between two states of another spiropyran showed a 35-fold increase for the open, protonated form.
