The electrical energy is currently used to regulate photosynthesis. But these strategies lack precision, hindering the full utilization of energy. Here, we developed an electrically activated photosynthesis system, using electrochemiluminescence (ECL) and conjugated polymer nanoparticles (PFTP-NPs). Attributing to matchable photophysical properties, we successfully used ECL emission of Ru(bpy)32+ and tripropylamine (TPA) to activate photosynthesis. Under ECL emission, the electron generation in chloroplast was accelerated. ATP and NADPH production in the light-dependent reaction increased by 466% and 200%, respectively. Additionally, PFTP-NPs were employed as light-harvesting materials and modified onto the chloroplasts. Due to superior light-harvesting and light-converting properties, PFTP-NPs further refined spectral matching between ECL and chloroplasts, enabling further photosynthesis regulation. As a result, the trapped energy and energy used for electron transfer increased by 7% and 24%, respectively. ATP and NADPH production increased by 16.9% and 3.9%, respectively. The successful demonstration holds immense potential for advancing photosynthesis regulation.
