1	Development of advanced cross conjugated systems and applications in ratiometric sensing: altering the electronic properties of cruciforms and poly(para-phenyleneethynylene)s to elicit differing reactivity and response Davey, Evan Andrew 13 May 2012 (has links) This research serves as a meticulous examination into cross-conjugated materials and how alterations of the frontier molecular orbitals can be utilized for applications in "chemical tongue" organic sensing devices. With conjugated materials being used in the development of new sensory devices for detection of metals, bacteria, and chemical warfare agents, the field of organic sensing is growing faster than ever. The purpose of this dissertation is to provide a precedence for the synthesis of new cross-conjugated compounds and outline potential applications of these materials as chemical sensors and molecular probes.
