Synthesis, Physical Properties and Applications of Bisanthene-based Near Infrared Dyes and Semiconductors

Bisanthene has good characters such as small bandgap, planar p system, to be as a good building block for electronics or to construct novel polycyclic aromatic hydrocarbons (PAHs). However, the investigation on bisanthene has not been so prosperous because of its photo-unstability and poor solubility. Based on the knowledge above, new soluble and stable bisanthene-based molecules and materials are the major research objectives in this thesis, which include several aspects: (1) Synthesis of new soluble and stable near infrared (NIR) dyes based on bisanthene by substitution at its active meso-positions with aryl or alkyne group. (2) To construct more extended p-systems based on bisanthene via Diels-Alder reaction with dienophiles at the bay regions. (3) n-type cyanated ovalene diimides (ODI-CN) was prepared and its application on organic field effect transistors (OFETs).
