Abstract

An increasing number of conjugated, organic molecules and polymers are finding application as materials for electronics and photonics due to their inherent synthetic flexibility, potential ease of processing and the possibility of tailoring material characteristics to suit a desired property.¹ To more efficiently design organic materials to specific tasks, it is necessary to understand how and to what degree alteration of molecular electronic structure affects materials properties. Investigation of a comprehensive series of synthetically related molecules and the relationship between their electronic and physical properties is perhaps the best approach to the rational design of useful organic materials. Hence, we have synthesized a complete series of conjugated, electronically varied molecules based on a tetraethynylethene (TEE, 1) framework. Study of the optical and electrical properties of these electronically diverse building blocks will aid in tuning specific properties for the ultimate formation of functionalized polytriacetylenes (PTAs, 2).
