In this paper a simple, casting solution technique for the preparation of two-imensional (2D) arrays of very-high molecular weight (MW) 1D-Pc supramolecular inorganic polymers is described. The solube fluoraluminium tetra-tert-butylphthalocyanine (ttbPcAIF) is synthesized and characterized, which can be self-assembeld to form 2D arrays of very-high MW 1D-Pc srupramolecular inorganic polymers. High-resolution transmission electron microscopy (HRTEM) demonstrates that the 1D-ttbPcAIF having a cofacial ring spacing of similar to 0.36 nm and an interchain distance of similar to.1.7nm, self-assembles into 2D-nanosheets (similar to 140 nm in length, similar to 20nm in width, and equivalent to MW of 3.2 x 10(5) g mol(-1)). The film cast from a 1,2-dichloroethane (DCE) solution shows a minimum hole-mobility of similar to 0.3cm(2-)V(-1)s(-1) at room temperature by flash-photolysis time-resolved microwave conductivity (TRMC) measurements and a fairly high dark dc-conductivity of similar to 1 x 10(-3) S cm(-1)
