Prof. Jinjia Xu from The University of Missouri- St. Louis of Chemistry & Biochemistry will present Advanced Functional Organic Materials for Electronic and Biomedical Applications
p-Conjugated polymers and organic molecules have gained significant attention over the past decade owing to their exceptional optoelectronic functions, good deformability, low weight, and stimuli responsiveness. They have been widely recognized and used as promising materials for active and smart materials in soft robots, emitters, sensors, and actuators. Despite tremendous progress made in improving charge carrier mobility and optimizing energy bandgap, our comprehensive understanding of the structure and properties of conjugated polymers and functional molecules – such as structural design, molecular alignment behavior, and the microphase separation phenomenon – remains limited. This knowledge gap hinders the predictive design of innovative functional materials capable of meeting the evolving demands of a wide range of future applications.
In my presentation, I will offer an overview of our endeavors in the systematic molecular design of organic functional materials for electronic and biomedical applications.
Specifically, I will discuss some of our latest efforts on
1. A helically-twisted ladder based on 9,9’-bifluorenylidene: synthesis, characterization, and carrier-transport properties
2. Room-Temperature Columnar Liquid Crystals from Twisted and Macrocyclic 9,9′-Bifluorenylidene Mesogen with Ambipolar Carrier Transport Properties
3. Zwitterionic Porous Conjugated Polymers as a Versatile Platform for Antibiofouling Implantable Bioelectronics
4. The additive-free viscoelastic conjugated polymers (VE-CPs) at room temperature, exhibiting a never-seen-before dynamic miscibility with self-restorable and mechanically induced fluorescence color changes.
I hope this talk will shed light on the exciting possibilities for the novel design of new soft and functional organic materials and encourage further research in this field.
