A Large Starphene Comprising Pentacene Branches.

Starphenes are attractive compounds due to their characteristic physicochemical properties that are inherited from acenes, making them interesting compounds for organic electronics and optics. However, the instability and low solubility of larger starphene homologs make their synthesis extremely challenging. Herein, we present a new strategy leading to pristine [16]starphene in preparative scale.

Non-invasive hemodynamic profile of early COVID-19 infection.

Introduction: Little is known about the systemic and pulmonary macrohemodynamics in early COVID-19 infection. Echocardiography may provide useful insights into COVID-19 physiopathology.

Methods: Twenty-three COVID-19 patients were enrolled in a medical ward.
