Design of Novel Organic Thin Film Transistors for Wearable Electronics
Abstract
The focus of this multidisciplinary, collaborative basic research programme has been on the development of a low cost process technology for depositing high-resolution patterned layers newly custom designed organic macrocyclic compounds -- thermotropic liquid crystalline zinc (II) phthalocyanine (ZnPc4) and lutetium (III) bisphthalocyanine (Lu(III)Pc2) derivatives both substituted with individual functional groups at peripheral and non-peripheral positions, respectively. Spin coated films of these molecules were employed as active organic semiconducting layers in the fabrication of organic thin film field-effect transistors (OTFT) and the effect of the grain boundary and interfacial traps at the gate dielectric has been carefully investigated. The radox reactions of (Lu(III)Pc2) films with biological cofactors have spectroscopically been studied for their use in health care. Emphasis is given on easy manufacturability and integration of mechanically flexible sensors over large areas which are suitable for multiple applications including health care, security and fashion industry.
