Isosteric Substitution Enables Rational Design of Two‐Dimensional Energetic Crystals
Advanced Science, Volume 13, Issue 39, 13 July 2026.Isosteric substitution transforms a classical nitro–amine motif into two‐dimensional aminofurazans with performance beyond TATB. ABSTRACT Two‐dimensional (2D) energetic crystals dissipate mechanical insult via interlayer slip, yet their molecular design space remains narrow.
