The Role of Chromophore Coupling in Singlet Fission

Popis výsledku v původním jazyce

Certain organic materials can generate two electron-hole pairs per absorbed photon in a process known as singlet fission and their use could revolutionize the prospects for solar energy, from dye-sensitized solar cells to solar cell bilayers to bulk heterojunctions. However, near perfect efficiency is needed in compounds that also have other requisite properties (strong visible light absorption, photostability, etc.). Most recent work focused on crystalline polyacenes, but limitations in stability, cost, and performance may hinder their practical application, and we are looking for additional structures. We describe rationally designed singlet fission chromophores and their covalent dimers, aggregates, and polycrystalline films, with two tasks in mind:(i) producing an ideal energy level structure and (ii) inducing the correct type and strength of chromophore coupling. For (i), theory suggests that two classes of chromophores, alternant hydrocarbons and biradicaloids, are likely to off
