Abstract
Dr Chi received her Bachelor degree in chemical engineering from Qiqihar University in 1998 and Masters degree in polymer chemistry from Changchun Institute of Applied Chemistry, Chinese Academy of Sciences in 2001. She did her PhD degree (summa cum laude) in chemistry at Max-Planck Institute for Polymer Research (with Prof. Gerhard Wegner) in 2001-2004 and continued as a Research Assistant under Prof Wegner’s supervision from 2004-2005.
I will briefly introduce the research work in my group at NUS. The talk includes four parts: (1) novel n-type acene-based semiconductors (e.g. 1-3); (2) high order acenes (e.g. 4); (3) triazatruxene-based liquid crystals and two-photon absorption chromophores (e.g. TAT-Tn) and (4) H-shaped low band gap ambipolar semiconductors (e.g. HT-Tn). I will discuss their synthesis, material properties and device applications.
