Polymer and small molecules, custom manufactured or adapted from catalog products, for vapor and printing processes

Seqens manufactures high-purity photo-and electro-active chemicals while offering reliable processes to answer custom needs for the production of OPD, OPV, OLED, OFET and OTFT materials. Our expertise in bringing lab innovations to industrial production guarantees time-to-market optimization.

Supporting material innovation

Seqens has more than 30 years of experience in developing and manufacturing specialty chemicals for electronics, directly benefiting from PCAS and Saint-Jean Photochemicals history. Thanks to seasoned scientists and state-of-the-art lab equipment, we are able to support development of electro- and photo-active materials. We also partner with technical and academic players to level up chemical process optimization, fine tune analytical methods, and carry out applicative testing.

Seqens supports material innovation for Organic PhotoDetectors (OPD), Organic PhotoVoltaic (OPV), Organic Light Emitting Diodes (OLED), Organic Field Effect Transistors (OFET), and Organic Thin Film Transistors (OTFT). We offer polymers and small molecules integrating the composition of active and transport layers, as well as electrodes and substrate materials. Our variety of tailor-made semiconductive and conductive molecules and polymers encompass polycarbazoles, polythiophenes, polyanilines, polyfluorenes, polypyrroles, and heterocyclic aromatic compounds. Along with our custom manufacturing offer, we specifically supply well renowned and patented polycarbazole derivatives such as PCDTBT.

Managing
tailor-made industrialization

Seqens is a favorite partner to bring new solutions to industrial scale with the best quality and the guarantee of an optimized time to market. Our teams closely collaborate with customers to understand their requirements and major hurdles all along the project. Favoring development success, we act transparently and put at your disposal our extensive industrialization process know-how.

Operating kilo-lab, pilot, and industrial production facilities, Seqens definitely is a key partner for scale-up support. We are able to conduct a wide range of chemical syntheses including cryogenic processes thanks to specific and flexible production equipment. From early stage to industrial scale, our chemical scientists develop and optimize analytical methods to guarantee the best follow-up of the product specifications.
