Sequential infiltration synthesis (SIS) is an emerging method for vapor-phase growth of inorganic materials within polymers that is utilized for hybrid organic-inorganic and inorganic nanostructure fabrication. The range of SIS applications was continuously expanding for the past decade. Fundamental understanding of precursor-polymer interactions is, however, essential in order to expand the use of SIS to addnl. chemistries and move beyond thin film polymer templates. This work utilizes d. functional theory (DFT) calculations and in-situ gravimetric anal. to probe the growth mechanism of tri-Me aluminum (TMA) within poly(Me methacrylate) (PMMA) and poly(2-vinyl pyridine) (P2VP). The theor. and exptl. anal. reveals that each precursor-polymer pair is characterized by a balance point temperature at which rates of forward and reverse precursor-polymer binding enable maximum mass gain at thermodn. equilibrium At short exposure times, mass gain is significantly influenced by the pressure profile of the process chamber. Mechanism comprehension enabled nanopatterning of previously unsuitable block copolymer (BCP), polystyrene-block-P2VP (PS-b-P2VP), at elevated temperatures It was proven possible to grow significant mass while maintaining the pattern, by stabilizing the morphol. via a single cycle at low-temperature SIS; thus, overcoming self-assembly sensitivity to temperature In the experiment, the researchers used many compounds, for example, 2-Isopropylpyridine (cas: 644-98-4HPLC of Formula: 644-98-4).
2-Isopropylpyridine (cas: 644-98-4) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.HPLC of Formula: 644-98-4
