One-Pot Synthesis and Excited-State Dynamics of Null Exciton-Coupled Diketopyrrolopyrroles Oligo-Grids
Bo, Y., Hou, P., Wan, J., Cao, H., Liu, Y., Xie, L., Guldi, D. M., Adv. Mater. 2023, 35, 2302664. https://doi.org/10.1002/adma.202302664 Exciton coupling in molecular aggregates plays a vital role in impacting and fine-tuning optoelectronic materials and their efficiencies in devices. A versatile platform to decipher aggregation-property relationships is built around multichromophoric architectures. Here, a […]Bo, Y., Hou, P., Wan, J., Cao, H., Liu, Y., Xie, L., Guldi, D. M., Adv.

Enhancing Built-in Electric Fields for Efficient Photocatalytic Hydrogen Evolution by Encapsulating C60 Fullerene into Zirconium-Based Metal-Organic Frameworks
Liu, L., Meng, H., Chai, Y., Chen, X., Xu, J., Liu, X., Liu, W., Guldi, D. M., Zhu, Y., Angew. Chem. Int. Ed. 2023, 62, e202217897. https://doi.org/10.1002/anie.202217897 High-efficiency photocatalysts based on metal-organic frameworks (MOFs) are often limited by poor charge separation and slow charge-transfer kinetics. Herein, a novel MOF photocatalyst is successfully constructed by encapsulating […]Liu, L., Meng, H., Chai, Y., Chen, X., Xu, J., Liu, X., Liu, W., Guldi, D. M., Zhu, Y., Angew. Chem. Int.
