Abstract :Novel symmetrical 3,6-bis[(25,26,27-tripropoxy-28-(3-(4-iodophenyl)propoxy)-p-tert-butyl calix[4]arene ethynyl]-9H-fluoren-9-one with a cone conformation was synthesized by palladium-catalyzed coupling of (25,26,27-tripropoxy- 28-(3-(4-iodophenyl)propoxy)-p-tert-butyl calix[4]arene and 3,6-diethynyl-9H-fluoren-9-one. Its structure was confirmed by FT-IR, 1H-NMR, and 13C-NMR spectroscopy, and elemental analysis and positive ion FAB mass spectrometry.Keywords : Synthesis, 3, 6-diethynyl-9H-fluoren-9-one, p-tert-butyl calix[4]arene, FAB mass, palladium-catalyzed
