摘要：

Two's company but three's allowed! An entropy-driven tristable molecular shuttle has been developed, where shuttling between two of three stations is brought about through a photochemical isomerization, but a further stable co-conformation is unexpectedly observed simply upon changing the temperature (the picture shows the molecular shuttle in one of the three possible co-conformations).
