An o-phenylenevinylene-bridged tetrapyrrolic macrocycle (2) was synthesized by means of a Horner–Wadsworth–Emmons reaction between benzylbisphosphonate and SEM-protected diformylpyrrole, followed by deprotection of the SEM groups. This conformationally flexible tetrapyrrole can be considered as an expanded calixpyrrole analogue, which acts as a receptor for the chloride and bromide anions in THF-d8, but undergoes deprotonation upon exposure to the fluoride anion.
