Investigation Of Synthetic Methods For Preparation Of 2O-Amino Derivatives Of 5-Amino- 1, 10-Phenanthroline: Applications To Cu+2 Based Impedance Sensors, Satish B. Chunchu

Master's Theses and Doctoral Dissertations

The main purpose of this project is to synthesize 2^o - derivatives of 5-amino-1, 10- phenanthroline (5-aphen) for application as self-assembled monolayers on gold interdigitated electrode array chips in standard impedance and impedance resonance-based Cu²⁺ sensors. Potential applications include monitoring Cu²⁺ leaching from anti-fouling coatings on ship hulls. The importance of the planned secondary alkyl amino derivatives will be to test their binding properties to the gold surface through dithiocarbamate linkages by monitoring the IDE impedance signal. Practical sensor development requires good impedance response, maximum binding to the gold IDE chip, and maximum long term stability of …
