The effects of intra- and inter-molecular interactions on the photophysics of platinum(II) complexes
Abstract
Square planar platinum(II) complexes have been the subject of intense study for several years due to their many unique properties and potential applications. Exploiting the emission of these complexes allows for a wide range of applications as spectroscopic probes and anticancer reagents. Manipulation of both intra-molecular and inter-molecular interactions allows one to tune the photophysical properties of compounds with great precision. Chapter one of this thesis will introduce the critical role of platinum(II) in medicinal chemistry and basic photophysics of platinum(II) complexes. Chapter two describes the synthesis and studies of a series of novel expanded framework polypyridine platinum(II) complexes that employ a little-explored method of intra-molecular modification. The majority of the compounds exhibit improved photophysics over the parent compound [Pt(trpy)Cl]+. Chapter three summarizes a body of work conducted by McMillin group members over the past several years and describes the synthesis and characterization of the missing members of the series. These complexes involving 4'-substituted trpy ligands, exhibit very impressive photophysics and utilize a well-recognized approach to intra-molecular modification. Chapter four describes the solid state photophysical properties of compounds synthesized by the Lu group. These compounds provide excellent examples of classic intermolecular interaction in Pt(II) compounds and MMLCT emission.
