Crosslinking Vinyl‐Addition Polynorbornenes via Difunctional Diazirines to Generate Low Dielectric‐Constant and Low Dielectric‐Loss Thermosets

Front Cover: 5G and 6G telecommunications devices operate at high frequencies, necessitating the use of photoactive polymer compositions with ultra‐low dielectric constants and dissipation factors. In article 2400200, Jeremy E. Wulff, Larry F. Rhodes, and co‐workers use electronically optimized diazirine reagents to crosslink and photopattern low‐dielectric poly(norbornenes).
