Sonodynamic and Bioorthogonal Sonocatalytic Thrombotic Therapy Based on AIE Cationic Tetranuclear Ir(III) Complex Nanoplatform Guided by NIR‐Chemiluminescence Imaging

open access: yesAdvanced Materials, EarlyView.
AIE‐active tetranuclear Ir(III) complex Ir‐4 as a sonosensitizer/sonocatalyst is formulated into a nanoplatform with an H2S donor. Ir‐4@S‐R NPs achieves combined endogenous NIR chemiluminescence imaging, sonodynamic therapy and release of H2S in situ by a bioorthogonal sonocatalytic reaction in vivo, achieving safe thrombolysis and anti‐inflammatory ...

Understanding the mechanism stabilizing intermediate spin states in Fe(II)-Porphyrin

open access: yes, 2017
Spin fluctuations in Fe(II)-porphyrins are at the heart of heme-proteins functionality. Despite significant progress in porphyrin chemistry, the mechanisms that rule spin state stabilisation remain elusive.

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Derivatized porphyrins and multi-porphyrin assemblies

open access: yes, 2018
Porphyrin-containing multi-component systems have served a key role in the study of molecular assembly and supramolecular chemistry. These systems, however, are often very difficult to prepare and new synthetic strategies towards their preparation are of great interest;This work describes a series of thiol-derivatized porphyrins and the corresponding ...
