Abstract

The solid-state structure of 4,7-bis((trimethylsilyl)ethynyl)benzo[c][1,2,5]thiadiazole reveals a dimeric structure with short S···N contacts, a motif that is shown to be common in electron-poor macrocycles of this type and that is likely to be a significant factor in the design of devices using materials based on these compounds.
