In article number 1707483, Qiang Zhang and co‐workers design and prepare porphyrin organic framework hollow spheres with well‐defined chemical structures of the organic frameworks. The as‐obtained hollow spheres serve as a desirable host for the sulfur cathode in lithium–sulfur batteries, enabling high capacity, long‐term stability, and excellent rate performance.
Organic frameworks represent an emerging family of advanced materials that can be precisely controlled at the atomic level. However, morphology control of organic frameworks remains perplexing and difficult, strongly limiting the advantages of organic frameworks in multiple practical applications. Herein, porphyrin organic framework hollow spheres (POF‐HSs) are fabricated by a template method as a...
