本文描述了一种简单的用于制备极高分子量（MW）1D-Pc超分子无机聚合物的二维（2D）阵列的铸膜溶液技术。合成并表征了可溶性四叔丁基氟铝酞菁（ttbPcAlF），其可自组装形成超高分子量的一维酞菁超分子无机聚合物二维阵列。高分辨率透射电子显微镜（HRTEM）表明，具有10.36 nm的共面环间距和101.7 nm的链间距离的1D-ttbPcAlF自组装成2D-纳米片（长度为140 nm，宽度为1020 nm，相当于3.2 × 105 g mol−1的MW）。由1，2-二氯乙烷（DCE）溶液浇铸的薄膜在室温下通过闪光光解时间分辨微波电导率（TRMC）测量显示出最小空穴迁移率为0.3 cm 2 V−1 s−1，并且暗直流电导率相当高，为0.1 × 10−3 S cm−1。
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.
