About Heading link
Research in the Ayitou Lab seeks to bridge knowledge gaps in photo-energy materials, photo-energy conversion/management, and photo-therapeutics. Fundamentally, our research elucidates the structure-photophysics relationship in novel organic light-harvesting systems.
Our lab uses advanced spectroscopy tools to investigate energy/exciton transfer in organic solid or organic-semiconductor materials. Photo-excitation of this class of novel (hybrid) materials, developed in our lab, would create excitons that can be exploited for various applications, viz., photo/energy conversion, catalysis, and photo-therapeutics.
Research Interest & Application 1
We design and synthesize novel heavy-atom-free organic chromophores by tuning their molecular aromaticity and spin state(s). These chromophores are utilized for light-initiated processes viz., energy transfer, sensitization, photo-medicinal applications, energy upconversion, etc.
Research Interest & Application 2
We are exploiting novel Photosensitizers (PS) (functionalized with other bio-active/pro-drug molecules) for synergistic photodynamic therapy and drug delivery applications. The synthesis and photochemical/photophysical investigations are carried out in our lab…and our collaborators perform the bio-assay investigations.
Outreach and Science-Community Advocate
Spectroscopy Bootcamp for Grade Students (SPEK12): SPEK12 Spectroscopy Bootcamp is a week-long outreach program that stimulates the curiosity of middle and high school students. The camp is free to participate in. Students can use state-of-the-art spectroscopy instruments to probe various light-induced processes encountered in many areas/fields (healthcare, space science, environment, forensics, law enforcement, etc.). This camp runs every summer on-site or online!
Schools/Students interested in this program must contact Dr. Ayitou @ UIC (for more information).
NOBCChE Chapter at UIC: Dr. Ayitou is the faculty advisor for the UIC Chapter of NOBCChE. This student organization aims to provide resources to students of color majoring in chemistry, chemical engineering, and related fields. This organization will host several campus and community events to promote chemical sciences and encourage underrepresented students to embrace STEM disciplines/research.
Anyone seeking to get involved can send an inquiry to Dr. Ayitou @ UIC
