“…Adamantane is a highly symmetrical and rigid tricyclic hydrocarbon with chair‐type cyclohexane rings as a structural unit, which is equivalent to the diamond lattice . In addition, the hydrogens on the bridgehead carbon atoms of adamantane molecular possess good chemical reaction activity, so that it is easier to take place substitution reaction to form the adamantane derivatives containing various characteristic functional groups . Thus, adamantly group can be introduced into silicone materials to improve refractive index and hardness.…”

The encapsulation of high power light emitting diode (LED) needs the silicone resins to have relative high refractive index and thermal-aging properties. Herein, high refractive index adamantane-based phenyl epoxy-silicone (APES) resins for LED encapsulation were synthesized by the sol-gel condensation of 1-adamantane methanol propyltrimethoxysilane-3-urethane, γ-(2,3-epoxypropoxy)propytrimethoxysilane and diphenylsilanediol. These adamantane-based silicone resins have multifunctional groups including adamantyl group, phenyl group, and epoxy group in order to meet the various requirements for LED encapsulation. Importantly, the adamantane group in the silicone resins benefits for high refractive index and anti-thermal properties.These APES resins were characterized by proton nuclear magnetic resonance and Fourier transform infrared spectroscopy. When APES resins were cured by methylhexahydrophthalic anhydride, they showed relatively high refractive index of 1.56, high hardness, and high thermal resistance. The encapsulated LED demonstrated high adhesion properties by red-ink tests. These merits make adamantane-based silicone resins promising candidates as LED encapsulation materials.

Polymer dielectrics with high energy density are of urgent demand in electric and electronic devices, but the tradeoff between dielectric constant and breakdown strength is still unsolved. Herein, the synthesis and molar mass control of three alternating [1.1.1]propellane‐(meth)acrylate copolymers, denoted as P‐MA, P‐MMA, and P‐EA, respectively, are reported. These copolymers exhibit high thermal stability and are semi‐crystalline with varied glass transition temperatures and melting temperatures. The rigid bicyclo[1.1.1]pentane units in the polymer backbone promote the orientational polarization of the polar ester groups, thus enhancing the dielectric constants of these polymers, which are 4.50 for P‐EA, 4.55 for P‐MA, and 5.11 for P‐MMA at 10 Hz and room temperature, respectively. Moreover, the high breakdown strength is ensured by the non‐conjugated nature of bicyclo[1.1.1]pentane unit. As a result, these copolymers show extraordinary energy storage performance; P‐MA exhibits a discharge energy density of 9.73 J cm–3 at 750 MV m–1 and ambient temperature. This work provides a new type of promising candidates as polymer dielectrics for film capacitors, and offers an efficient strategy to improve the dielectric and energy storage properties by introducing rigid non‐conjugated bicyclo[1.1.1]pentane unit into the polymer backbone.
