Morphology-Controlled Self-Assembly and Synthesis of Biopolyimide Particles from 4-Amino-L-phenylalanine was written by Hirayama, Thawinda;Kumar, Amit;Takada, Kenji;Kaneko, Tatsuo. And the article was included in ACS Omega in 2020.COA of Formula: C13H12O6 This article mentions the following:

Self-assembling polyimides (PIs) having diketopiperazine (DKP) components were synthesized by polycondensation of a 4-amino-L-phenylalanine (4APhe) dimer, an aromatic diamine newly designed in this study. The amino acid-derived PIs showed high thermal resistance, with a 10% weight loss temperature (T_d10) of 432°C at the maximum, and did not show any glass transition below the thermal decomposition temperature The poly(amic acid) (PAA) precursors formed nanospheres upon reprecipitation over dimethylacetamide into water. The nanospheres were then added to solvents with different polarities and sonicated to induce deformation of the spherical forms into spiky balls, flakes, or rods. The PAA particle morphologies were retained in the PIs after the two-step imidization. Finally, the PI particles with self-assembling DKP moieties were formed, and their morphologies were fine-tuned using different mixed solvents. In the experiment, the researchers used many compounds, for example, 6-(2,5-Dioxotetrahydrofuran-3-yl)-4-methyl-7,7a-dihydroisobenzofuran-1,3(3aH,6H)-dione (cas: 73003-90-4COA of Formula: C13H12O6).

And the article was included in Organic Electronics in 2012.Category: tetrahydrofurans This article mentions the following:

We have developed photo-sensitive, low-temperature processable, soluble polyimide (PSPI) gate insulator with excellent resistance to the photo-patterning process. The PSPI was synthesized through one-step condensation polymerization of monomers 5-(2,5-dioxytetrahydrofuryl)-3-methyl-3-cyclohexene-1,2-dicarboxylic anhydride (DOCDA) and 3,5-diaminobenzyl cinnamate (DABC). PSPI thin film, fabricated at 160°C, has a dielec. constant of 3.3 at 10 kHz, and leakage c.d. of <1.7 × 10^-10 A/cm², while biased from 0 to 100 V. PSPI could be easily patterned by selective UV-light exposure and dipping into γ-butyrolactone. To investigate the potential of the polyimide as the photo-patternable gate insulator, we fabricated pentacene OTFTs and confirmed the PSPI’s resistance to the photo-patterning process. The photo-patternable polyimide shows promise as gate dielecs. for OTFTs. In the experiment, the researchers used many compounds, for example, 6-(2,5-Dioxotetrahydrofuran-3-yl)-4-methyl-7,7a-dihydroisobenzofuran-1,3(3aH,6H)-dione (cas: 73003-90-4Category: tetrahydrofurans).

Synthesis and characterization of 9,9-bis(4-hydroxyphenyl and 4-aminophenyl)dibenzofluorenes: Novel fluorene-based monomers was written by Seesukphronrarak, Surasak;Kawasaki, Shinichi;Kuwata, Shigeki;Takata, Toshikazu. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2019.Application of 73003-90-4 This article mentions the following:

Two novel 9,9-difunctionalized fluorene-type monomers, 9,9-bis(4-hydroxyphenyl- and 4-aminophenyl)-2,3:6,7-dibenzofluorenes, are synthesized by the reaction of dibenzenzofluorenone with phenol and aniline. These monomers are used for the preparation of polyester and polyimide as the typical polymers to evaluate the property change such as thermal stability caused by the benzene rings fused to the fluorene skeleton with keeping good solubility, in comparison with the polymers derived from simple fluorenone. In fact, these two new polymers have the fairly enhanced thermal stability and refractive index value along with satisfactory solubility in organic solvents, enough to emphasize the fusion effect. In the experiment, the researchers used many compounds, for example, 6-(2,5-Dioxotetrahydrofuran-3-yl)-4-methyl-7,7a-dihydroisobenzofuran-1,3(3aH,6H)-dione (cas: 73003-90-4Application of 73003-90-4).

Magnetic drug delivery system is one of the most important strategies for cancer diagnosis and treatment. In this study, a novel theranostic system was fabricated based on cyclodextrin nanosponge (CDNS) polymer anchored on the surface of Magnetite nanoparticles (Fe₃O₄/CDNS NPs) which was then decorated with folic acid (FA) as a targeting agent (Fe₃O₄/CDNS-FA). Curcumin (CUR), a hydrophobic model drug, was next loaded into the cyclodextrin cavity and polymeric matrix of CDNS (Fe₃O₄/CDNS-FA@CUR). The system was fully characterized. The in vitro release study revealed pH-sensitive behavior. Cytotoxicity assays indicated a negligible toxicity for CUR free Fe₃O₄/CDNS-FA NPs against both of M109 cancerous cells and MCF 10A normal cells. CUR-loaded Fe₃O₄/CDNS-FA NPs exhibited higher toxicity against M109 cancerous cells than MCF 10A normal cells (p < 0.05). Fe₃O₄/CDNS-FA@CUR NPs resulted in much more cell viability on normal cells than pure CUR (p < 0.05). Moreover, blood compatibility study showed minor hemolytic activity. In vitro MRI studies illustrated neg. signal increase in cells affirming acceptable diagnostic ability of the nanocarrier. The T₂ MR signal intensity for Fe₃O₄/CDNS-FA@CUR NPs in M109 cells was around 2-fold higher than that of MCF 10A cells. This implies two times higher selective cellular uptake of the Fe₃O₄/CDNS-FA@CUR NPs into M109 cell compared to MCF 10A. The multifunctional nanocarrier could be considered as promising candidate for cancer theranostics because of the smart drug release, selective cytotoxicity, suitable hemocompatibility, and proper T₂ MRI contrast efficiency. In the experiment, the researchers used many compounds, for example, 6-(2,5-Dioxotetrahydrofuran-3-yl)-4-methyl-7,7a-dihydroisobenzofuran-1,3(3aH,6H)-dione (cas: 73003-90-4Product Details of 73003-90-4).

Fabrication of imide hybrid nanocomposites using amine modified oligosiloxanes nanoclusters was written by Lee, Tae-Ho;Kim, Jeong Hwan;Bae, Byeong-Soo. And the article was included in PMSE Preprints in 2006.Related Products of 73003-90-4 This article mentions the following:

Fabrication of inorganic-organic hybrid nanocomposites (IOHN) using well-defined nanoclusters has attracted much attention over the last decade. In particular, amine groups have very promising properties for roles as binding sites for DNA, microcrystals, diamond surfaces and photo-functional organic mols. The amine modified oligosiloxanes nanoclusters (AONC) are synthesized as useful and effective well-defined nanoclusters to fabricate IOHN. AONC are easily prepared in a single step by barium hydroxide monohydrate catalyzed condensation reactions between diphenylsilanediol (DPSD) and 3-aminopropyltrimethoxysilane (APTS). AONC are well-defined nanoclusters below 2 nm and their chem. modifications are easily achieved by changing precursors. We report here the synthesis of amine modified oligosiloxane nanoclusters (AONC), methacryl modified AONC and vinyl cinnamate modified AONC. Addnl., we report the fabrication of photo-functional hybrid nanocomposites derived from AONC, methacryl modified AONC and vinyl cinnamate modified AONC. Three different photo-functional hybrid nanocomposites are fabricated using AONC, derivatives of AONC and dianhydrides. (1)colorless imide hybrid nanocomposites, (2) photo-patternable imide hybrid nanocomposites and (3) photo-reactive hybrid nanocomposites for photo-alignment of liquid crystals.

Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Related Products of 73003-90-4
