Altering synthetic fragments to tune the AIE properties and self-assemble grid-like structures of TPE-based oxacalixarenes

Abstract

TPE-based oxacalixarenes were synthesized by one-pot condensation. Their AIE properties and self-assembled structures in the solid state can be tuned effectively by utilization different building blocks in the synthetic process. Moreover, the oxacalixarene 1a can be assembled into nanoparticles in THF/water and can be used as a detector for nitroaromatic explosives, such as TNP.
