Abstract

In this paper a simple, casting solution technique for the preparation of two-dimensional (2D) arrays of very-high molecular weight (MW) 1D-Pc supramolecular inorganic polymers is described. The soluble fluoroaluminium tetra-tert-butylphthalocyanine (ttbPcAlF) is synthesized and characterized, which can be self-assembled to form 2D arrays of very-high-MW 1D-Pc supramolecular inorganic polymers. High-resolution transmission electron microscopy (HRTEM) demonstrates that the 1D-ttbPcAlF, having a cofacial ring spacing of ∼0.36 nm and an interchain distance of ∼1.7 nm, self-assembles into 2D-nanosheets (∼140 nm in length, ∼20 nm in width, and equivalent to MW of 3.2 × 105 g mol−1). The film cast from a 1,2-dichloroethane (DCE) solution shows a minimum hole-mobility of ∼0.3 cm2 V−1 s−1 at room temperature by flash-photolysis time-resolved microwave conductivity (TRMC) measurements and a fairly high dark dc-conductivity of ∼1 × 10−3 S cm−1.
