Organic electronics based on the thin films, including organic thin film transistors (OTFTs), organic light emitting diodes (OLEDs), organic photovoltaics (OPVs) and organic electrochromic devices (OECs) are envisioned both great interest in academia and industry. The properties of organic semiconductor materials are directly governed by the molecule structures. In this talk I will present the recent work conducted in our lab for molecular design strategies and semiconductor device engineering. Examples include searching high mobility organic semiconductors and dielectric materials (~50 cm2/Vs with Vt of 0.5 V) with unique properties for OTFT and OLED applications; high fluorescence and fine tuning color efficiency of electrochromic materials with D-A conjugated polymers for dual-mode display and military camouflage applications; energy level controlling of hole transport materials and interface engineering of materials for perovskite solar cell applications. Detailed studies on the electrochemical and photo-electronic properties as well as the device performance of these new semiconductors and interface materials are discussed.
