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.

Abstract
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.File in questo prodotto:
