Photochemical upconversion in water

Chem. Commun., 53(85), 11705–11708.

By: K. El Roz n & F. Castellano n 

topics (OpenAlex): Luminescence and Fluorescent Materials; Perovskite Materials and Applications; Radical Photochemical Reactions
TL;DR: This investigation achieves the goal of identifying appropriate chromophore combinations that function in pure water in the absence of hydrophobic hosts or surfactant additives using combinations of water soluble Ru(ii) metal-to-ligand charge transfer (MLCT) sensitizers in concert with 9-anthracenecarboxylates and 1-pyrenecarboxylate in neat H2O.

Homogeneous Photocatalytic H2 Production Using a RuII Bathophenanthroline Metal‐to‐Ligand Charge‐Transfer Photosensitizer

Khnayzer, R. S., Olaiya, B. S., El Roz, K. A., & Castellano, F. N. (2016, May 30). ChemPlusChem, Vol. 81, pp. 1090–1097.

By: R. Khnayzer *, B. Olaiya*, K. El Roz n & F. Castellano n 

author keywords: electron transfer; hydrogen; photocatalysis; ruthenium; time-resolved spectroscopy
topics (OpenAlex): Metalloenzymes and iron-sulfur proteins; CO2 Reduction Techniques and Catalysts; Electrocatalysts for Energy Conversion
TL;DR: H2 production by photocatalysis was independently monitored by using a high-throughput photochemical reactor equipped with pressure transducers, gas chromatogram, and a mass spectrometer for detection, which illustrated that the composition yields high turnover numbers (TONs).

Light-Driven Hydrogen Evolution by BODIPY-Sensitized Cobaloxime Catalysts

Bartelmess, J., Francis, A. J., Roz, K. A. E., Castellano, F. N., Weare, W. W., & Sommer, R. D. (2014, April 11). Inorganic Chemistry, Vol. 53, pp. 4527–4534.

By: J. Bartelmess n, A. Francis n, K. Roz n, F. Castellano n , W. Weare n & R. Sommer n 

Contributors: J. Bartelmess n, A. Francis n, K. El Roz n, F. Castellano n , W. Weare n & R. Sommer n 

topics (OpenAlex): Advanced Photocatalysis Techniques; Metalloenzymes and iron-sulfur proteins; Porphyrin Metabolism and Disorders
TL;DR: It is concluded that accessing the photoexcited triplet state of the BODIPY chromophore by introducing heavy atoms is necessary for efficient electron transfer in this system, enabling catalytic hydrogen generation. (via Semantic Scholar)
