Chirality amplification
WebMar 3, 2024 · Strong chiral amplification occurs between the enantiopure sergeants and the achiral soldiers. The resulting supramolecular copolymers exhibit comparable photodetection efficiency to that of the homopolymeric ones, with a 90% decrease in the enantiopure compound consumption. Therefore, cooperative supramolecular … WebThis review is devoted to the chiral optical behavior of films of racemic polymers whose chirality is induced by cocrystallization with nonracemic (also temporary) guest molecules. We provide example
