Research and Teaching Interests

The Grieco lab aims to develop a fundamental understanding of mixed ionic-electronic conduction in conjugated polymers for ion-charge signal transduction and energy storage. Inspired by bioelectronic and solar energy storage/conversion applications, our research lies at the interface between Physical Chemistry, Materials Chemistry, and Engineering. We develop and apply in situ time-resolved optical spectroscopic methods for probing the elementary processes that occur during mixed ionic-electronic conduction in polymers.

Research in the Grieco lab focuses on characterizing the electronic structure and environment of charge carriers in mixed ionic-electronic conductors as they undergo electrochemical changes in working devices. Our strategy is to develop new spectroscopic approaches to study the complex interplay of ionic and electronic transport, and their dependence on the dynamic nanoscale environment and morphology of the polymers. Through spectroscopy, we aim to learn how to design the chemical structure and morphology of polymers for maximizing their performance in electrochemical devices.

Our spectroscopy instruments include:

  • Ultrafast broadband visible/near-infrared pump-probe spectroscopy (~400 - 2500 nm), including single-shot transient absorption capabilities.
  • Visible/near-infrared absorbance spectrometer (multichannel, high spectral acquisiton rates)

 

Keywords: Time-resolved spectroscopy, physical/analytical chemistry, polymers, energy, materials, bioelectronics, spectro-electrochemistry.
