By Kirill Khamidovich Zhuravlev, Ph.D. Washington State University May 2004 Chair: M. D. McCluskey Conjugated organic molecules are important components in solid-state optoelectronic devices and laser dyes. Changes in the conformations of these molecules affect the optical emission wavelengths. In order to probe the conformation of conjugated molecules, infrared (IR) spectroscopy was performed ...
The research in the short-chain organic -conjugated molecules has become one of the most interesting topics in the fields of chemistry. These compounds have become the most promising materials for the optoelectronic device technology. The use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. The control of the band gap of th...
A series of three donor molecules (DPP-B, DPP-N and DPP-P) based on diketopyrrolopyrrole (DPP) sharing the similar backbone D-π-A-π-D have been investigated. In these molecules, substituents such as pyrene, naphthalene benzene act electron donating end groups, DPP central core unit thiophene has used a bridge between acceptor fragments. Theoretical calculations carried out with help density fun...
