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 m2 g–1.
The open frameworks were favorable for doping with iodine and followed
with the improved charge carrier mobility. The compressed pellet of
I2@FL-COF-1 exhibited a high Seebeck coefficient of 2450
μV K–1 and power factor of 0.063 μW
m–1 K–2 at room temperature, giving
the first example of COFs’ potential application as thermoelectric
materials.
