This thesis describes spectroscopic studies on photoinduced CT in donor-bridge-acceptor (DBA) systems and their derivatives. Throughout this work, we employ femtosecond transient absorption spectroscopy to capture the excited state dynamics in ensembles of isolated molecular systems in solution. Specifically, we have studied the organic DBA derivatives based on boron dipyrromethene (BODIPY) and on perylenemonoimide as well as organic-inorganic hybrid assemblies based on surface-anchored perylene derivatives and perovskite nanoplatelets. The main focus is on understanding the interplay between the molecular structure and the resulting CT behavior, paving the way for tailoring and optimizing these systems for specific applications.
