摘要
Organic electrochromic polymers are attractive materials for low-power optoelectronic devices due to their tunable optical properties, fast switching, flexibility, and compatibility with solution-based processing.1 Further improvement and diversification of their performance can be achieved by combining them with inorganic nanomaterials such as quantum dots (QDs). However, the preparation of such hybrid systems is often complicated by poor compatibility between the organic and inorganic components, requiring additional functionalization, formulation, or deposition steps that limit scalability.2 Here, we present a pyridine-functionalized polythiophene platform designed to enable direct integration of QDs within a processable electrochromic polymer. Using a low-cost oxidative polymerization method (FeCl₃), the polymer is produced with scalability and economic viability in mind, achieving a narrow polydispersity (PDI = 1.5). The polythiophene backbone provides the conjugated structure required for efficient electrochromic behavior, while the pyridine units act as coordination sites for the QD surface. This enables the QDs to be incorporated directly into the polymer formulation by mixing in solution. The resulting mixture can be processed using deposition techniques such as spray coating for integration into electrochromic devices. The hybrid material retains a pronounced reversible electrochromic effect with an enhancement of spectroscopic properties and provides a route towards integrating inorganic functionality into electrochromic polymer films.
