Applications of Molecular Switching and Logic

The Thesis begins with an introduction of molecular logic gates and switches induced by various stimuli in chapter 1. <br><br>Then a population analysis is presented in chapter 2 for polymer beads which are tagged with multi-valued logic gates, YES, (2YES + PASS 1), (YES + PASS 1), (YES + 2PASS 1) and PASS 1 with H+ input, 700 nm near-infrared fluorescence output and 615 nm red light excitation. The gates carry an azaBODIPY (azaborodipyrromethene) fluorophore and an aliphatic tertiary amine as the H+ receptor where necessary.

The H+-induced fluorescence enhancement factors are signatures which identify a given bead type within a mixed population when examined with a fluorescence microscope. Therefore, molecular computational identification (MCID) succeeds in encoding objects which are too small for radiofrequency identification (RFID) tagging. <br><br>PolypyridylRu(II) complexes, which have inspired many research fields and applications, are shown in chapter 3 to be inclusively bound in water with submicromolar affinities by a new class of anionic triangular cyclophanes.
