A synthetic methodology is reported that functionalizes C60 and C70 fullerenes with dihydroazepine rings by a cascade reaction encompassing rhodium-catalyzed cycloisomerization of 1,5-bisallenes [4+2] cycloaddition. This transition metal-catalyzed provides versatile step-economical approach to the synthesis 6,7-membered polyheterocyclic fullerene adducts. Electrochemical characterization produc...

Electrical energy usage has drastically increased in recent decades, resulting significant demand for renewable sources, especially solar. With the development of technology, extracting from photovoltaic (PV) modules become easier and more economical. The performance PV array decreases under an intermittent environment such as partial shading conditions (PSCs), causing fluctuations power output...
