A novel open-bowl pyramidal compound cyclotriveratrylene-carbazole (CTV-CZ) was designed and synthesized. Its absorption and emission spectroscopic properties in different organic solvents were characterized. Three absorption peaks of CTV-CZ around 235 nm, 260 nm and 290 nm were observed. The fluorescence emission peaks were at about 353 nm and 368 nm using a solution of ∼10(-7)M CTV-CZ. The intermolecular interaction between CTV-CZ and fullerene (C₆₀) was studied in detail by UV-vis absorption and fluorescence spectra. CTV-CZ could associate with C₆₀ to form supramolecular complex with 1:1 molar ratio and the binding constant was estimated to be 5.0(6) × 10(4)M(-1) by fluorimetry. The formation of inclusion complex for CTV-CZ and C₆₀ was further confirmed by (1)H NMR and cyclic voltammetry. The downfield shift of protons of CTV-CZ in its (1)H NMR spectrum and the decrease of redox currents on addition of C₆₀ showed that photo induced electron transfer (PET) occurred from the electron donor CTV and CZ units to the electron acceptor C₆₀.
