“…In fact, theoretical simulations showed that the ZT value could be very high (∼20) in such low‐dimensional conducting systems . This unusually high value of ZT was obtained based on the assumption that two types of electron‐phonon interactions exist simultaneously in this quasi‐one‐dimensional system.…”

The abundance of solar thermal energy and the widespread demands for waste heat recovery make thermoelectric generators (TEGs) very attractive in harvesting low-cost energy resources. Meanwhile, thermoelectric refrigeration is promising for local cooling and niche applications. In this context there is currently a growing interest in developing organic thermoelectric materials which are flexible, cost-effective, eco-friendly and potentially energy-efficient. In particular, the past several years have witnessed remarkable progress in organic thermoelectric materials and devices. In this review, thermoelectric properties of conducting polymers and small molecules are summarized, with recent progresses in materials, measurements and devices highlighted. Prospects and suggestions for future research efforts are also presented. The organic thermoelectric materials are emerging candidates for green energy conversion.

“…Such structural character ensures them intrinsically high carrier mobilities and high electrical conductivity (up to 2.1 × 10 5 S m –1 at room temperature), , and therefore the charge-transfer complexes present great potential as high-performance thermoelectric materials. Theoretical simulations have also shown that the ZT value of charge-transfer complexes could be very high (∼20) due to the special electron–phonon interactions existing in such a system . However, the study of charge-transfer complexes in thermoelectrics is stagnant due to the low ZT values, which is mostly attributed to the high thermal conductivity in organic single crystal and the difficulty of optimizing carrier concentrations .…”

A series of copper phthalocyanine (CuPc)-based organic small molecules were prepared through vapor-phase reaction. Nanoscale phase separation was observed with tunable CuPc and copper phthalocyaninato iodide (CuPcI) phase content by changing the iodine ratio. The Seebeck coefficient of the samples was significantly enhanced, which is considered to be attributed to the enhanced surface polarization effect due to the formation of a great number of nanoscale interfaces between the CuPc phase and the CuPcI phase. In addition, these nanointerfaces also gave rise to increased phonon scattering and therefore significantly reduced the lattice thermal conductivity of the small-molecule samples. As a result of the combination of the synergistically optimized electrical and thermal transport properties, the maximum ZT value reaches 3.0 × 10 −2 at room temperature, which is among the highest values for small-molecule charge-transfer complex reported so far. Our results shed light on optimizing the thermoelectric performance of organic small molecules by introducing nanoscale phase separations and tailoring the nanoscale interfaces.
