WebbThe melt-memory is a common phenomenon in polymer crystallization where recrystallization of a semicrystalline polymer depends profoundly on the nature of its initial melt state.1–21 If a semi-crystalline polymer is melted and then recrystallized, the time required for recrystallization, the shape of the recrystallization isotherm, and the Webb13 apr. 2024 · Furthermore, the high crystalline COFs exhibit excellent performance in the photocatalytic asymmetric alkylation of aldehydes. The monomer crystal-induced method not only represents a new route for the synthesis of crystalline COFs but also sheds light on the mechanism of the formation of COFs.
