Robert Burns Woodward's publications exhibit a beauty and majesty infrequently seen in the scientific literature. Excerpts from Woodward's publications are presented along with a discussion of his literary personality and the effect of his writings on his contemporaries and on the style of the chemical literature that followed.

A bis(NiII‐porphyrinyl)aminyl radical with meso‐C6F5 groups was prepared as a spin‐delocalized stable aminyl radical with a doublet spin state. Upon addition of pyridine, both NiII centers became hexacoordinated by accepting two axial pyridines, which triggered a spin‐state change of the NiII centers from diamagnetic (S=0) to paramagnetic (S=1). The resulting high‐spin NiII centers interact with the aminyl radical ferromagnetically to give rise to an overall sextet state (S=5/2). Importantly, this coordination‐induced spin‐state switching can be conducted in a reversible manner, in that washing of the high‐spin radical with aqueous hydrochloric acid regenerates the original doublet radical in good yield. Flick the switch: An aminyl radical bridged NiII‐porphyrin dimer is a doublet (S=1/2) but can be reversibly switched to a sextet (S=5/2) upon addition of pyridine ligands by coordination‐induced spin‐state switch (CISSS) owing to ferromagnetic interaction between the high‐spin NiII centers and aminyl radical.

The author reflects on the importance of sustainable chemistry in the energy policies that may be formulated by several countries. The author mentions the condition of energy production in several countries including the reliance of Germany on fossil fuels and the exploitation of the U.S. of shale gas. The author discusses the challenges in achieving sustainable energy production through the utilization chemicals.
