A general photochemical synthesis of large thiohelicenes
containing nine and eleven rings is discussed along with the organisation
of racemic thiohelicenes in crystals: heterochiral assembling is dominant
except in the nine-ring system where interactions involving terminal ring S
atoms favour the segregation of close-packed homochiral molecules in
planes.
