Sulfated hyaluronic acid has been shown to have protective effects against growth factors such as FGF2 and FGF1, and it is expected to be applied not only as a substitute for sulfated polysaccharides in the fields of regenerative medicine and tissue regeneration but also in areas where sulfated polysaccharides have not been able to achieve results until now. Tokyo Chemical Industry provides sulfated hyaluronic acid, which is hyaluronic acid that has been sulfated. The degree of sulfation of sulfated hyaluronic acid can be controlled by adjusting the reaction. Currently, we have two types of sulfated hyaluronic acid with adjusted degrees of sulfation available.

At Tokyo Chemical Industry, we have prepared low molecular weight n-type organic semiconductors TU-1 and TU-3 [T3924], which have high electron mobility. TU-1 is mainly suitable for vacuum deposition processes, while TU-3 is suitable for coating processes, allowing for use according to application. These organic semiconductors were developed by the group of Tokunaga et al., and applications for high-performance complementary transistor circuits using combinations with p-type semiconductors have also been reported. We have also fabricated organic field-effect transistor (OFET) devices using TU-1 and TU-3 with vacuum deposition and spin-coating methods, respectively, achieving electron mobilities exceeding 1 cm²/Vs in both cases.

This is a metal complex polymer with electrochromic properties (EC) that changes from purple to colorless when a voltage is applied. It is characterized by its "memory effect," which allows it to maintain the displayed color even when the power is turned off. By using this polymer in EC devices, applications such as smart glass and smart films are anticipated. 【Features】 ■ Color changes sensitively with the application of voltage (electrochromism) ■ Maintains displayed color even when the power is off (memory effect) *For more details, please refer to the PDF document or feel free to contact us.
