Abstract: meso-Ethynyl extended aryl-picket calix[4]pyrroles 2 and 3 are designed and synthesized by directly anchoring arylethynyl groups at diametrically opposed meso-positions. The critical roles of direct ethynyl linkers are manifested through the isolation of unexpected host-anion… read more here.
