Molecular triads comprised of boron dipyrrin-C60 Dyad connected to either an energy or electron donating entity to probe sequential energy/electron transfer events.

Wijesinghe, Channa A.; D'Souza, Francis (Wichita State University. Graduate School, 2009-05-01)

In natural photosynthesis two major processes, absorption of light energy by antenna system and transportation of that light energy to the reaction center take place efficiently. There is a growing interest to mimic these ...
The preparation of charged anion receptors to bind anionic components of bacterial membranes

Koralegedara, Manjula B. (Wichita State University. Graduate School, 2010-04-23)

A receptor able to selectively bind a phosphatidylglycerol (PPG) head group is an attractive synthetic target as a modular component of an antimicrobial therapeutic. The major challenge to the preparation of such receptors, ...
Production and collision induced dissociation of gas-phase, water and alcohol coordinated uranyl complexes containing halide or perchlorate anions

Chien, Wen-Fang Winnie; Van Stipdonk, Michael J.; Groenewold, Gary S.; Gresham, Garold L.; Anbalagan, Victor (Wichita State University. Graduate School., 2005-04-22)
Recent advances in cyanoscorpionate chemistry: complexes with CO(II), MN(II), and NI(II)(cyclam)

Bullinger, John C.; Moore, Curtis E.; Eichhorn, David M. (Wichita State University. Graduate School., 2008-04-25)

In the past, electronic and magnetic materials have been atom based materials made up of metals or metal-oxides. Functionally,these atom based materials are extremely efficient, however, they are very expensive to synthesize, ...
Separation of metallic and semi conducting SWNTs by density gradient ultracentrifugation and formation of donor-acceptor hybrids using porphyrins

Das, Sushanta K. (Wichita State University. Graduate School, 2010-04-23)

Occurrence of photo induced electron transfer in donor-acceptor self-assembled Zinc porphyrin (ZnP) and C₀M₀CAT single walled carbon nanotube (SWNT) nanohybrid has been demonstrated. C₀M₀CAT (6,5) and C₀M₀CAT(7,6) SWNT ...
Solution properties of the iron(II) tris-bipyrazine cation

Kirgan, Robert A.; Rillema, D. Paul (Wichita State University. Graduate School., 2005-04-22)
Spectroscopic investigation of hydrogen atom transfer in the McLafferty rearrangement

Kerstetter, Dale R.; Leavitt, Christopher M.; Groenewold, Gary S.; Steill, Jeffrey D.; Oomens, Jos; Van Stipdonk, Michael J. (Wichita State University. Graduate School., 2008-04-25)

In this study, wavelength-selective infrared multiple-photon photodissociation (WS-IRMPD) was used to study the transfer of an H atom in a gas-phase unimolecular rearrangement reaction. The reaction studied was the ...
A study on the mechanism of the Parkinsonian-causing drug 1-methyl-4-phenylpyridinium (MPP+)

Samms, Warren C.; Perera, Rohan P.; Wimalasena, D. Shyamali; Turla, K.M.; Wimalasena, Kandatege (Wichita State University, 2005-04-22)
Synthesis of asymmetrically substituted push-pull phthalocyanines as potential photodynamic therapy agent

Amin, Anu N.; Maligaspe, Eranda (Wichita State University. Graduate School, 2010-04-23)

Over the past decade, photodynamic therapy (PDT) has begun to gain worldwide attention either as a primary or as an alternate treatment for solid cancers.1The success of the treatment largely depends upon the tumor-selectivity ...
