General description

i-PMMA can be prepared from t-C4H9MgBr. Structure of crystalline isotactic poly(methyl methacrylate) (i-PMMA) was investigated by X-ray diffraction and infra red spectroscopic techniques.

Application

The polymeric blend of isotatic (i-) poly-(methyl methacrylate) & 6,13-bis(triisopropylsilylethynyl) pentacene can be used to prepare thin films transistors (TFTs).

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
