A greener tetraphenylporphyrin synthesis and metallation: an undergraduate teaching experiment
Summary
In this experiment, 5,10,15,20-tetraphenyl-21H,23H-porphyrin (H2TPP) is synthesized on the microscale using an optimized procedure with a research-grade microwave apparatus (CEM Discover). This experiment can also be extended to the para-substituted phenyl derivatives.
Metalloporphyrins, with an array of metals, can then be synthesized using greener routes including mechanochemical methods (with ...

Sustainable Preparation of an Earth-abundant Metal Acetylacetonate Complex
Summary
This experiment highlights the synthesis of the Earth-abundant metal complex, Fe(acac)3 (acac = acetylacetonate), using an approach that is greener than traditional published syntheses. Students will also have an opportunity to determine the magnetic susceptibility of this complex and to learn about NMR spectroscopy.

The Synthesis of Zinc Copper Indium Sulfide Quantum Dots
Summary
In this experiment, ZnCuInS2 quantum dots of differing sizes are prepared and analyzed by UV-Vis and fluorescence spectroscopy. The ZnCuInS quantum dot synthesis is inherently greener than common nanoparticle syntheses, e.g. CsPbX3 or CdSe, because the use of Pb and Cd is avoided. Due to their tunability and excellent optical properties, quantum dots have allowed for the development of QLED ...
