Transition metal complexes have unique photophysical and photochemical properties which will play significant roles in a wide range of biological and artificial systems as photocatalysts, solar energy harvesters, ligand emitters, sensors and so on. Comprehensive studies on the excited state dynamics of transition metal complexes are of great interest for developing new material and devices. Photoinduced structural change represents a primary excited state dynamic process that determines the photophysical and photochemical properties of transition meal complexes. My work is focus on application of a series of pyrazolated bridged platinum dinuclear complexes, which are also called butterfly-like platinum (II) complexes due to the molecule structure. I have studied the excited state dynamics of these butterfly-like platinum (II) complexes, which show interesting photoinduced structural change and environment dependent luminescence. Using these new platinum binuclear complexes with controlled excited state properties, there are some sensors, such as phase change sensor, viscosity sensor and temperature sensor can be achieved. === A Thesis submitted to the Department of Chemical and Biomedical Engineering in partial fulfillment of the requirements for the degree of Master of Science. === Summer Semester 2015. === July 15, 2015. === Includes bibliographical references. === Biwu Ma, Professor Directing Thesis; Daniel T.
