By incorporating active optical materials into polymer-based platforms, it becomes possible to engineer devices capable of light generation, modulation, and detection, while preserving mechanical adaptability and compatibility with large-area processing. Within this context, luminescent organic molecules and two-dimensional (2D) semiconductors stand out as two highly complementary material classes: the former offer chemical tunability and emission control through molecular design, while the latter combine strong light–matter interaction with excitonic effects inherent to their atomically thin nature. Their integration paves the way for the development of hybrid light-emitting systems with enhanced performance and new opportunities for flexible photonic architectures. This thesis explores different material strategies for achieving light emission in flexible environments, combining three main lines of experimental work: the optical characterization of π-conjugated molecular emitters embedded in polymer thin films; the study of semiconducting and magnetic 2D materials such as MoS2, WSe2, and FePS3; and the integration of hybrid 2D–molecule systems within polymer matrices. A custom-built confocal microscopy system, combined with steady-state and time-resolved photoluminescence spectroscopy, is used to investigate emission dynamics, spectral coupling, and exciton modulation across these systems. By embedding the active components in polymeric hosts, the work not only demonstrates the potential of hybrid configurations for enhanced and tunable light emission, but also addresses relevant aspects for their scalable integration, including photostability, spectral control, and interface compatibility. Altogether, this thesis contributes to the experimental foundation for the use of molecular and 2D materials in the next generation of flexible and polymer-based optoelectronic devices.","abstract_html":"Over the last decade, plastic optoelectronics has emerged as a promising response to the growing demand for photonic technologies that are not only lightweight and flexible, but also energy-efficient and cost-effective.
