Biphenyl and Terphenyl Lactone pH-Driven Molecular Switches
Riel, Asia Marie; Carlson, Erik; Ahola, Zach (2013-05)The physical properties of biaryl-containing compounds are known to be highly dependent on molecular geometry. Two 6H-benzo[c]chromen-6-one derivatives were synthesized, where a lactone "tether" between the two phenyl rings ... -
Comparison of Isomeric Aryldibenzopyrylium Salts as Highly Conjugated Planar Dyes
Meyer, Samantha; Charlesworth-Seiler, Eva; Dahl, Bart J. (2019-05)Planar conjugated organic compounds can be incorporated into a variety of applications due to their unique optical properties. One such class of these compounds contains the pyryliumunit, which is capable of reversible ... -
Design, Synthesis, and Characterization of "Smart" Donor-Acceptor Biaryls
Carlson, Erick J.; Riel, Asia Marie (2011-05)The purpose of this project is to investigate the synthesis of tethered organic biaryl systems for ultimate application in sensing and molecular electronics. -
Oligoethylene Glycol Solubilized Crankshaft Lactone Molecular Switches
Charlesworth-Seiler, Eva; Torres, Yunuen; Dahl, Bart J. (2018-02-05)Molecules that can reversibly convert between two forms exhibiting different properties. Interconversion between states does not happen spontaneously, but in response to certain stimuli. -
Oligoethylene Glycol Substituted Isomeric Pi- Expanded Coumarins with Crankshaft Architectures
Goedhart, Carly; Dahl, Bart J. (2017-03-03)The physical properties of terphenyl-containing compounds are known to be highly dependent on molecular geometry, specifically the dihedral angle. Compounds capable of dihedral angle modulation should be useful molecular ... -
Pi-Expanded Coumarins with Switchable Propeller Geometries
Hintz, Heather A.; Sortedahl, Nicholas J.; Dahl, Bart J. (2017-03-09)The focus of this project is analyzing planar conjugated molecules as molecular geometric switches. Our mission is to synthesize and study different classes of pi-expanded oligocoumarins with Crankshaft and Propeller ... -
Progress Toward a Propeller-Shaped Oligophenyl Lactone with Reversible Geometry Switching
Sortedahl, Nicholas J.; Meeuwsen, Brian T. (2013-05)Planar conjugated organic molecules have unique spectroscopic and electronic properties. This study focused on molecules containing the 6H-benzo[c]chromen-6-one subunit because they should be both planar and conjugated, ... -
"Smart" Biphenyl Lactone Containing a Nitro Acceptor and Methoxy Donor
Riel, Asia Marie (2012-04)The purpose of this study was to investigate the synthesis of tethered organic biaryl systems for ultimate application in sensing and molecular electronics. -
Synthesis and Characterization of "Smart" Biaryl Sultines
Wiltgen, Hilary E. (2012-04)Biphenly-containing compounds, applicable to many nanoscience applications, such as sensors and molecular machines, can be imagined to exist in two states: non-planar or planar. Most biphenyl containing compounds have been ... -
Synthesis and Comparison of Various 6-aryldibenzo[b,d]pyrylium salts
Kitzrow, Jonathan (2015-04)Our objective is to synthesize different 6-aryldibenzo [b,d]pyrylium salts. By varying the R groups, we can examine the communication between electron donors and acceptors across extended ring systems. -
Synthesis and Halochromism of 6-Aryldibenzo [b,d] Pyrylium Salts
Patrow, Joel; Prust, Erin; Carlson, Erik (2013-05)The purpose of this study was to synthesize different 6-aryldibenzo[b,d]pyrylium salts and to examine their optical changes to pH environment along with their spectroscopic properties. -
Synthesis and Study of Cyano-Donor/Methoxy-Acceptor Biphenyl and Terphenyl Lactones
Carlson, Erick J. (2012-04)The purpose of this study was to explore a biaryl compound capable of dihedral angle modification through a reversible tethered lactone bridge. These compounds will find themselves pertinent to the fields of molecular ... -
Synthesis and Study of Monodispersed Oligophenyl Lactones
Sortedahl, Nicholas J. (2012-04)The goal of this study was to create and study different oligophenyl lactones that vary in both shape and size. These compounds should prove to be useful in applications such as solar cells, light emitting diodes, and ... -
Synthesis of Deuterated, Protected Amino Acids Tyrosine and Serine
Meeuwsen, Brian T. (2013-05)In the United States, 1 in every 8 women will be diagnosed with breast cancer at some point in their lives. Although adjuvant therapies have improved therapy success after lumpectomy or mastectomy, therapeutic choices are ...
