摘要: The photophysical properties of emissive conjugated polymer (CP) chains are compared to those linear J-aggregates. two systems share many in common, including a red-shifted absorption spectrum with increasing chain/aggregate length, enhanced radiative decay rates (superradiance) relative single monomer/molecule, and several vibronic signatures involving the vinyl-stretching mode common molecules. In particular, scaling 0–0/0–1 photoluminescence ratio rate inverse square root temperature red-phase polydiacetylene is also characteristic linear, disorder-free strong resemblance traced excitonic band structure; one-dimensional direct gap semiconductors as well J-aggregates, exciton curvature positive at gamma point (k = 0).
