Workshop 7: Nanoscale Structure-Property Relationships in Conjugated Polymers

Date: Wednesday, May 20, 2009

Organizer(s): Mircea Cotlet (BNL-CFN), cotlet@bnl.gov; Hsing Lin Wang (LANL), hwang@lanl.gov

Location: Center for Functional Nanomaterials, Bldg. 735

Description: Conjugated polymers are an exciting class of polymers with great potential in optical, electronic and biosensing applications. Since their discovery in the late 1970, tremendous progress has been noticed in the synthesis, processing and characterization of conjugated polymers. There is unified consensus that the electronic and optical properties of these polymers are strongly dependent on the polymer chain structure and conformation. Therefore, control and manipulation of the polymer structure with the aim of improving the properties of conjugated polymers is a challenging task which requires deep understanding of the relationship between nanoscale polymer structure and electronic/optical properties. This workshop will focus on nanoscale investigations of the structural and optical properties of conjugated polymers with single molecule spectroscopy and X-ray methods, development of novel synthetic and processing methods for controlling the electronic and optical properties of conjugated polymers, and the use of conjugated polymers in energy-related applications. Audience: polymer chemists, material scientists, spectroscopists, physicists, theoretical
