Abstract

Abstract : Amplified Spontaneous Emission In article number 2206723, Juan Cabanillas‐González, Johannes Gierschner, Jinyi Lin and co‐workers report on how the spontaneous and stimulated emission properties of conjugated polymer blends are promoted through exciton transport disruption. The cover illustrates two alike polymer assemblies, the right one bearing two phenyl twisting units that reduce backbone planarity and hinder packing, leading to a concomitant reduction both in exciton diffusion and annihilation losses.
