2018 Spring Talk: Two-Dimensional Covalent Polymers and Frameworks (Prof. Donglin Jiang) @ Sapp Lecture Hall
Apr 6 @ 3:00 pm – 4:00 pm

Abstract:
Two-dimensional covalent polymers and organic frameworks are a class of crystalline polymers that enable the incorporation of organic building blocks into periodically aligned structures. In recent years, we have explored the design principle, synthetic reactions, structural diversity, functional design and materials applications. One significant feature is that the merge of covalent bonds and noncovalent interactions enables the precise control over primary and high-order structures. The geometry-directed covalent bonding enables the growth of two-dimensional atomic layer in which the primary-order structures are precisely controlled. The noncovalent π-π interactions guided by the total crystal stacking energy encode the ordered primary-order structure into high-order structures to construct periodically aligned polymer skeletons and nanosized unidirectional channels. In this seminar, I will discuss the chemistry, opportunity and challenges of COFs.

About the Speaker:
Donglin Jiang obtained his Bachelor’s degree from Zhejiang University and his Ph.D. from the University of Tokyo in 1998. He began his academic carrier as an assistant professor at the University of Tokyo, and was involved in developing functional polymers based on dendritic architectures until 2000, when he was appointed as the group leader of the Japan Science and Technology Agency (JST), the Exploratory Research for Advanced Technology (ERATO) project on AIDA Nanospace. In 2005, he moved to the Institute for Molecular Science, National Institutes of Natural Science as an associate professor to start his independent laboratory. In 2016, he moved to Japan Advanced Institute of Science and Technology (JAIST) as a full professor. In 2018, he joined the Department of Chemistry, Faculty of Science, National University of Singapore as a tenured full professor. His current research interests include two-dimensional covalent polymers and frameworks, including their chemistry, physics, and materials.

Origins of Frank-Kasper and Quasicrystal Phases in Diblock Copolymer Melts

Abstract:
Block polymers have captured the interest of scientists and engineers for more than half a century. In general, the phase behavior of diblock copolymers, the simplest category of such self-assembling macromolecules, has been accepted as thoroughly understood. Recent experiments with low molecular weight diblock copolymers have revealed remarkable phase complexity in the limit of asymmetric compositions, 0.15 < fx < 0.25, where fx signifies the volume fraction of the minority block. Small-angle x-ray scattering (SAXS) measurements conducted in the vicinity of the order-disorder transition (ODT) temperature have revealed the formation of several low symmetry Frank-Kasper phases and a dodecagonal quasicrystal as a function of thermal processing history. Remarkably, when heated above the ODT temperature the liquid micelles retain a memory of the ordered state, which returns upon cooling. These finding will be discussed in the context of the occurrence of low symmetry crystals in soft and hard materials. About the speaker: Frank S. Bates is a Regents Professor and a member of the Chemical Engineering and Materials Science department at the University of Minnesota. He received a B.S. in Mathematics from SUNY Albany and M.S. and Sc.D. degrees in Chemical Engineering from MIT. Between 1982 and 1989 Bates was a member of the technical staff at AT&T Bell Laboratories then joined the University of Minnesota where he served as department Head from 1999 to 2014. Bates conducts research on a range of topics related to polymers, with a particular focus on the thermodynamics and dynamics of block polymers, blends and solutions He was elected to the US National Academy of Engineering in 2002, the American Academy of Arts and Sciences in 2010, and the National Academy of Sciences in 2017.
