Interdisciplinary Faculty Panel Presents Research at CAS Scholarship Series

An interdisciplinary panel of faculty members will present their research at the next session of the ongoing College of Arts and Sciences Scholarship Series on Tuesday, March 13. Participants include Susana Case, professor of behavioral sciences; Ana Petrovic (pictured at right), assistant professor of life sciences; and Patty K. Wongpakdee, assistant professor of fine arts. Discussion will range from Case's poetry collection, to Petrovic's research on molecular chirality, to Wongpakdee's insight on resurfacing graphics, which explores unconventional designs and how they stimulate viewers beyond paper's passive surface.

Excerpt of Ana Petrovic's technical research:

The transfer of chirality from a guest molecule to an achiral host is of a significant interest, especially when upon chiral induction the response of the complex can report the guest’s absolute configuration (AC). The tweezer methodology relies on a stereo-differentiating host/guest complexation between bis-porphyrin tweezer and chiral substrate containing two sites of coordination. This typically results in an exciton-split circular dichroism (CD) signal, diagnostic of guest’s AC.

Recently, it was shown that the molecular modeling predictions of a preferred interporphyrin helicity of the complex can assist the correlation between the experimental CD with the AC. The presentation will focus on scope of application of a novel, sterically encumbered, melamine based Zn-porphyrin tweezer.
