Synthesis and properties of zirconium-based porphyrin metal organic frameworks
上海师范大学学报. 自然科学版Porphyrins are ubiquitous in nature and are of great interest due to their excellent photophysical and electrochemical properties. However, intrinsic defects of porphyrins, such as instabilities, self-quenching, and poor water solubility, limit its ...

Advanced Materials Interfaces, EarlyView.CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...

Porphyrins as Theranostic Agents from Prehistoric to Modern Times
Theranostics, 2012 Long before humans roamed the planet, porphyrins in blood were serving not only as indispensable oxygen carriers, but also as the bright red contrast agent that unmistakably indicates injury sites.

Advanced Optical Materials, EarlyView.Large Faraday rotation at room temperature is observed in thin films of discotic copper (Cu2+: 3d9) and vanadyl (VO2+: 3d1) enaminoketone complexes. The large Verdet constant originates from a high density of paramagnetic centers, metal‐ligand p−d hybridization and π orbitals involved in optical transitions (identified by DFT calculations), as well as ...
