- 요약The field of chemistry has a long history of studying charge transfer and its potential application towards addressing a myriad of problems including but not limited to solar energy harvesting, organic photovoltaic construction, and more recently, quantum information science. Organic donor-acceptor systems have been of particular interest because of their versatility and synthetic tunability. To understand the full range of applications for a system, it is important to have and implement the correct methods of instrumentation. In this work, charge transfer dynamics are studied in solution, polycrystalline film, and single crystal samples of organic donor-acceptor systems using absorption, emission, and magnetic resonance techniques. The systems studied span a wide range for this work, from charge transfer mediated singlet fission in crystalline terrylene-3,4-dicarboximide (TMI), to symmetry breaking charge separation in 1,6,7,12-tetra(4'-t-butylphenoxy)perylene(3,4:9,10) bis(dicarboximide (tpPDI), to the generation of spin correlated radical pairs via radical pair intersystem crossing in donor-chromophore-acceptor molecules such as BDX-ANI-xy-NDI, where BDX is 2,2,6,6-tetramethylbenzo[1,2-d;4,5-d]bis[1,3]dioxole, the ANI chromophore is 4-(N-piperidinyl)naphthalene-1,8-dicarboximide, the NDI acceptor is naphthalene-1,8:4,5-bis(dicarboximide), and xy is a 2,5-xylyl spacer. There are also additional details given about the construction and implementation of an optically detected magnetic resonance (ODMR) instrument. From this body of work, common threads were determined about how a variety of perturbations such as temperature, structure, and geometry effected the overall process of electron transfer. From this, each system studied can be understood and optimized towards a unique application.
