Abstract :

To promote the performance for 3D printing and photoelectric devices, we have to study what conducts triplet exciton transport through the organic electronics. The ability of exciton transport can be quantified by the exciton diffusion coefficient (D) and length of diffusion (Ld), we thus estimate triplet exciton diffusion parameters for a series of platinumbased metallopolymers, pPtPh, pPtPh(CH2) and pPtBP, with a concentration-based exciton quenching method. With regard to the mechanism of transport, temperature dependent dynamics of the triplet exciton is investigated to distinguish the role of interchain transport in the conjugated system compared to interchain hopping transport in the conjugation interrupted systems. We demonstrate that an enhanced triplet diffusion coefficient in the fully conjugated polymer compared to the conjugation-interrupted structure is found as a result of lower activation energy (Ea). By contrast, the electronic coupling in conjugation-interrupted system is less due to the lower electronic coupling constant (HAB).
