4,4',7,7 '-Tetrabuty1-5,5',6,6'-tetracyano-2,2'-bis(benzo-1,3-dithio12-ylidene) (3-Bu) was prepared and mixed with 4,5-bis(2,6-dimethylphenoxy)-phthalonitrile (4), which was treated with lithium alkoxide at 120 C to produce diphthalocyanine linked with a TTF unit. The structure of the product was determined by NMR and MALDI-TOF-MS. The optical and electrochemical properties were examined by UV-vis spectra and cyclic voltammetry.

3,6-Dibutylphthalonitrile (3) fused with a TTF unit was prepared and treated with lithium in n-pentanol to produce octabutyltetrakis(tetrathiafulvaleno)phthalocyanine (5). The structure of the product was determined by 1 H NMR and FAB MS. Electrochemical and opticalproperties of compound (5) were estimated by cyclic voltammetry and UV-vis spectroscopy.
NMR, FAB MS, and MALDI TOF MS. The 1H NMR measurement was performed in chloroform-d at around 55 °C because of their higher aggregative property. Electrochemical and opticalproperties of 8a and 8b were examined by cyclic voltammetry and UV-vis and MCD spectroscopy. Molecular orbital calculations succeeded in reproducing the observed absorption spectrum of tetrakis(tetrathiafulvaleno)phthalocyanine.
