Semiconducting Molecules


Semiconducting molecules are organic compounds which exhibit semiconducting properties. Semiconducting molecules are composed of carbon-based organic compounds, unlike traditional semiconductors like silicon which are inorganic materials.

Features and Properties

  • Tunable conductivity. Semiconducting molecules can conduct electricity. Their properties can be tuned by modify the chemical structure, allowing precise control over their conductivity.
  • Low cost-manufacturing. Low cost, solution-based processing methods can be used leading to reduced device manufacturing costs. Semiconducting molecules are also generally cheaper to produce than inorganic semiconductors.
  • Flexibility. Organic molecules are more flexible than inorganic materials, enabling the fabrication of flexible or stretchable devices.

Explore our small-molecule semiconductors for use as emmitters and interlayers in TADF-based OLEDs, active materials in OFETs, and as interface materials to perovskites. Maximize your device efficency by fabricating and testing new devices in a glove box environment.

Fluorescence and Phosphorescence Fluorescence and Phosphorescence

Fluorescence and phosphorescence are types of photoluminescence. Photoluminescence refers to radiative emissions where the absorbance of a photon is followed by the emission of a lower energy photon. The main empirical difference between fluorescence and phosphorescence is the time in between absorbance and the emission of photons. Fluorescence is where a material absorbs a photon, and almost immediately emits a lower energy photon.

organic light emitting diodes Organic Light Emitting Diodes

Organic light emitting diodes are thin film devices that convert electrical energy into visible light. In OLED devices, electrons and holes are injected into the organic medium and recombine radiatively via electroluminescence (EL). The colour of the light emitted is dependent on the molecular structure of the organic material. This can be easily customized to make a wide range of wavelengths thanks to the endless configurations of organic molecules.
