Metalloporphyrin Conjugates
In article number 2301596, Matteo Tommasini, Juan Cabanillas‐González, and co‐workers reveal the photophysics of a fused nanographene–metalloporphyrin. The diagram shows the unveiled relaxation pathways of excited states. Photoexcitation populates ligand‐centered singlets, transitioning via intersystem crossing to metal‐centered triplets, then relaxing to ligand‐centered...
Porphyrins, a type of heterocyclic aromatic compounds consisting of tetrapyrroles connected by four substituted methine groups, are appealing building blocks for solar energy applications. However, their photosensitization capability is limited by their large optical energy gap, which results in a mismatch in absorption toward efficient harvesting of the solar spectrum. Porphyrin π‐extension by edge‐fusing...
Two‐dimensional titania nanosheets have been utilized to fabricate 2D titania‐based mesoporous silica through a controlled sol‐gel method, which can further serve as a robust and versatile template to construct various 2D heterostructures via a nanocasting technology. 2D titania‐based CdS has been fabricated. This heterostructure manifests an excellent H2‐production rate of 285 μmol·h−1 under visible‐light...
