Fields of Interest:
Research in the Reczek group spans several areas of Organic and Materials Chemistry, including Organic Synthesis, Supramolecular Chemistry, Crystal and Liquid Crystal design, and Organic Photovoltaics. We are broadly interested in the design, synthesis, and study of molecules which self-assemble, via non-covalent interactions, to exhibit new and unique properties. These properties are studies for potential application in new materials, specifically in the areas of molecular electronics and photovoltaics. Current projects include:
1) Synthesis and functionalization of anthracene diimides. Naphthalene and perylene diimides are two classes of electron-deficient aromatic molecules that have generated recent interest as components in Organic Materials and Molecular Electronics. The intermediate anthracene diimides show similar promise, but are relatively unexplored, largely due to difficulty in their synthesis. We are developing chemistry for the facile and versatile synthesis of anthracene diimides and related derivatives.
2) Structure-property relationships in aromatic-aromatic charge-transfer interactions. The face-to-face association (pi-pi stacking) of certain electron-rich and electron-deficient aromatic molecules leads to formation of complexes with a new charge-transfer absorbance band. This absorbance is associated with the excitation of an electron form the HOMO of one molecule to the LUMO of the complementary molecule. We are interested in discerning how changes in the position of substituents and/or molecular orbitals of component molecules, affect the charge-transfer properties of the self-assembled complex.
3) Aromatic donor-acceptor complexes as components of low-cost solar cells. The need to develop new photovoltaic chemistries for the efficient and affordable conversion of sunlight into electricity is a challenging problem of considerable importance. We are currently exploring the utility of aromatic donor-acceptor complexes as components of low-cost solar cells.
All research is carried out with undergraduate researchers, and a commitment to the training and development of the next generation of curious, innovative, creative thinkers and scientists.
