General Description

Pentadecan-8-amine, also known as octadecylamine, is a long-chain primary amine with the chemical formula C15H33NH2. It is a white to light yellow solid with a faint odor, and it is insoluble in water but soluble in organic solvents. Pentadecan-8-amine is commonly used as an intermediate in the production of surfactants, emulsifiers, corrosion inhibitors, and lubricants. It can also be used in the synthesis of specialty chemicals, pharmaceuticals, and agricultural products. Additionally, it is used as a conditioning agent in hair care products and as an anti-caking agent in powdered food products. Furthermore, pentadecan-8-amine is used in the manufacturing of quaternary ammonium compounds for use in fabric softeners, antimicrobial agents, and textile treatments.

Carborane-perylene diimide derivative and synthesis method thereof, sensing array based on derivative and preparation method and application of sensor array

The invention discloses a carborane-perylene diimide derivative and a synthesis method thereof, a sensing array based on the derivative and a preparation method and an application of the sensor array,and belongs to the technical field of small-molecular fluorescent sensing thin film materials. The carborane-perylene diimide derivative is placed in a solution, is assembled into a fiber structure with relatively large specific surface, and then is transferred to different substrate surfaces, so as to obtain the sensing array composed of a variety of fluorescent thin films; the sensing array canbe sensitive to sense six important drug gases, and drug samples have no need of any treatment; at the same time, through array combination, the interference of common interferents is eliminated thoroughly. The operation is simple, and the reaction conditions are mild. The prepared fluorescent sensing thin film has good stability and long service life, and is an excellent drug gas sensing thin film array. With combination use of the thin film and commercial fluorescent instruments, the drug gases can be sensitively detected. In addition, the drug gas special detection instrument can be developed through the device of the sensing thin film.

Chemical engineering of donor-acceptor liquid crystalline dyads and triads for the controlled nanostructuration of organic semiconductors

Multi-segregated columnar structures provide a geometrically ideal scheme for ambipolar organic semiconductors, but are not easy to design. A set of novel materials with dyad and triad architectures based on 2 different discotic cores is reported and the conditions of emergence of such complex structures are investigated. The designed molecules associate together electron-donor triphenylene cores (D) and perylene or naphthalene diimides as acceptor moieties (A), both entities being linked via alkyl chain spacers. The evaluation in solution of their HOMO/LUMO energy levels by cyclic voltammetry demonstrates the preservation of the individual features of the D and A units. Their thermal and self-organization behaviors were studied by polarized-light optical microscopy, differential scanning calorimetry, temperature-dependent small-angle X-ray scattering and dilatometry, which permitted detailed investigation of the self-organization behaviour. These D-A compounds turned out to spontaneously self-organize into columnar mesophases at room temperature, with the D and A moieties segregated into either alternated stacks within mixed columns or in distinct columns, the latter providing an ideal configuration for 1D hole and electron transport pathways. In view of potential applications of the triad/dyad template, thin films of these self-organized materials were also probed by atomic force microscopy and grazing incidence X-ray scattering.

Synthesis and antimicrobial activity of symmetrical two-tailed dendritic tricarboxylato amphiphiles

Two series of water-soluble, symmetrical two-tailed homologous dendritic amphiphiles-R2NCONHC((CH2)2COOH)3, 2(n,n), and R2CHNHCONHC((CH2)2COOH)3, 3(n,n), where R = n-CnH2n+1-were synthesized and compared to R″NHCONHC((CH2)2COOH)3, 1(n), R″ = n-CnH2n+1, to determine whether antimicrobial activity was influenced by total or individual alkyl chain lengths, and whether antimicrobial activity depends on hydrophobicity or tail topology (one or two). In a broad screen of 11 microorganisms, 2(n,n) and 3(n,n) generally displayed higher minimal inhibitory concentrations (MICs) than 1(n) against growth as measured by broth microdilution assays. Chain-length specificity was observed against Candida albicans as 1(16), 2(8,8), and 3(8,8) showed the lowest MIC in their respective series. The one case where two-tailed compounds displayed the lowest MICs-3(10,10), 15 μM; 3(11,11), 7.2 μM; and 3(12,12), 6.9 μM-was against Cryptococcus neoformans.
