One key element in chemistry is understanding the chemical properties of a molecule so that its interactions with itself, other atoms or molecules, or its environment is well known. This knowledge alone allows the chemist to innovate and invent and thereby change the world. Light surrounds and sustains our lives; thus it is vital to understand how light interacts with common and newly synthesized materials. In this thesis the photophysical properties of newly synthesized materials will be discussed to give an overview of the many ways in which light interacts with the chemical materials composing our everyday lives. General photophysical phenomena will be discussed along with the spectroscopic devices and techniques used to explore said phenomena. The molecules to be discussed are Indolizine-Squaraine based dyes with potential use as a biological imaging dye, fac-tris(2-phenylpyridine) iridium(III) or Ir(ppy)3, and BisMethoxyMethylPhenyl BoraFluorene (BMMBBF) with potential use as an OLED (organic light emitting diode). The spectroscopic properties such as absorption, emission, fluorescent lifetime, stokes shift, quantum yield, molar absorptivity, and vibrational modes will be explored through the use UV-Vis-NIR, Raman, and IR spectroscopy. The molecules will be studied in the solid and solution state and environmental effects will be surveyed. The molecules studied were found to be appropriate for their desired purposes according to their photophysical properties.
