Organic
semiconductors have great potential as flexible thermoelectric materials.
A fluorene-based covalent organic framework (FL-COF-1) was designed
with the aim of creating an enhanced π–π interaction
among the crystalline backbones. By the introduction of fluorene units
into the frameworks, the FL-COF-1 had high thermal stability with
a BET surface area over 1300 m<sup>2</sup> g<sup>–1</sup>.
The open frameworks were favorable for doping with iodine and followed
with the improved charge carrier mobility. The compressed pellet of
I<sub>2</sub>@FL-COF-1 exhibited a high Seebeck coefficient of 2450
μV K<sup>–1</sup> and power factor of 0.063 μW
m<sup>–1</sup> K<sup>–2</sup> at room temperature, giving
the first example of COFs’ potential application as thermoelectric
materials.
