For the immediate detection of strong gaseous alkalis and acids, colorimetric textile sensors based on halochromic dyes are highly valuable for monitoring gas leakages. To date, colorimetric textile sensors for dual-gas detection have usually been fabricated by electrospinning methods. Although nanofibrous sensors have excellent pH sensitivity, they are difficult to use com. because of their low durability, low productivity, and high production costs. In this study, we introduce novel textile sensors with high pH sensitivity and durability via a facile and low-cost screen-printing method. To fabricate these textiles sensors, Dye 3 and RhYK dyes were both incorporated into a polyester fabric. The fabricated sensors exhibited high detection rates (<10 s) and distinctive color changes under alk. or acidic conditions, even at low gas concentrations Furthermore, the fabricated sensors showed an outstanding durability and reversibility after washing and drying and were confirmed to contain limited amounts of hazardous materials. Thus, our results show that the fabricated textile sensors could be used in safety apparel that changes its color in the presence of harmful gases.

The article was titled 《Synthesis and optical characterisation of platinum(II) poly-yne polymers incorporating substituted 1,4-diethynylbenzene derivatives and an investigation of the intermolecular interactions in the diethynylbenzene molecular precursors》, and you may find the article in New Journal of Chemistry.Name: 1,4-Diethynyl-2,5-dimethoxybenzene The information in the text is summarized as follows:

A series of 1,4-diethynylbenzene derivatives, H-CC-R-CC-H with R = C6H3NH2 (I), C6H3F (II), C6H2F2-2,5 (III), C6F4 (IV), C6H2(OMe)2-2,5 (V) and C6H2(OC8H17-n)2-2,5 (VI) were synthesized and their crystal structures were determined by single crystal (I, II, III, IV) or powder (V, VI) x-ray diffraction. The CCH···πCC hydrogen bonds dominating structure H-CC-R-CC-H are gradually replaced by CC-H···F ones with the increase of fluorination (II → IV), or completely replaced by CCH···N and NH···πCC bonds in I, and CCH···O in V and VI. The related platinum-based polymers, trans-[-Pt(PnBu3)2-CC-R-CC-]n (R = as above and C6H4,) were prepared and characterized by spectroscopic methods and thermogravimetry, which show that the amino and methoxy derivatives have lowest thermal stability whereas the fluorinated ones exhibit increasing thermal stability with increasing fluorination. Optical spectroscopic measurements reveal that substituents on the aromatic spacer group do not create strong donor-acceptor interactions along the rigid backbone of the organometallic polymers. In addition to this study using 1,4-Diethynyl-2,5-dimethoxybenzene, there are many other studies that have used 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Name: 1,4-Diethynyl-2,5-dimethoxybenzene) was used in this study.

1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. Name: 1,4-Diethynyl-2,5-dimethoxybenzene They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however.

Application In Synthesis of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid. The article was titled 《Concomitant HPLC analysis of adapalene and nadifloxacin in the presence of glycolic acid》. The information in the text is summarized as follows:

Reversed phase HPLC-UV is the most common anal. method applied in pharmaceutical anal., but there are cases when its versatility is challenged, such as simultaneous separation of analytes with very different polarity and lipophilicity. A fast HPLC-UV method for the simultaneous determination of nadifloxacin (NDX) and adapalene (ADP) in the presence of glycolic acid (GA) was developed and anal. performances of the method were verified. Different alkane-type reversed phases (RP8 and RP18 columns, with different lengths and particle sizes) and different mobile phases were tested. Finally, a C18 column (33 x 4.6 mm, 3 mm) and a mobile phase consisted of 15 mM orthophosphoric acid solution and acetonitrile were selected. Determinations were performed with a run time of 4 min. The method was linear, accurate and precise over the selected concentration ranges of ADP and NDX. The developed method can be used for rapid quantification ADP and NDX without GA interference for in vitro release studies from topical formulations, through different types of diffusion membranes.

The article was titled 《An atom-economical and regioselective metal-free C-5 chalcogenation of 8-aminoquinolines under mild conditions》. The information in the text is summarized as follows:

A general and simple metal-free protocol for expedient C-H functionalization leading to the regioselective generation of C-5 chalcogenated 8-aminoquinoline analogs I [R = H, Me, 5-(((tert-butoxy)carbonyl)amino)pentan-2-yl; R1 = H, OMe, Me; R2 = Ph, Pr, 4-chlorophenyl, etc.; Z = S, Se] in up to 90% yield at room temperature (25 °C) has been established. This methodol. is an eco-friendly approach to the atom-economical utilization of diaryl/dialkyl chalcogenides R2ZZR2 for direct access to chalcogenated quinolines and is scalable to the gram scale without considerable decrease in the yield of the product. It represents a practical alternative to the existing metal-catalyzed functionalization of 8-aminoquinoline derivatives with broad functional group tolerance. The controlled experiments suggest that the reaction possibly proceeds through an ionic pathway at room temperature Furthermore, the potentiality for the functionalization of free amines in chalcogenated-8-aminoquinolines I provides an attractive perspective for further elaboration of the amine substituent through chem. manipulations. The applicability of the standardized method has been augmented through late-stage antimalarial drug diversification of primaquine analogs.

The title complex class with an Earth-abundant metal ion has been repeatedly suggested as a chromophore and potential photosensitizer on the basis of quantum chem. calculations Synthesis and photophys. properties of the parent complex [Fe(pbpy)(tpy)]+ (Hpbpy=6-phenyl-2,2′-bipyridine and tpy=2,2′:6′,2′′-terpyridine) of this new chromophore class are now reported. Ground-state characterization by X-ray diffraction, electrochem., spectroelectrochem., UV/Vis, and X-ray spectroscopy in combination with DFT calculations proves the high impact of the cyclometalating ligand on the electronic structure. The photophys. properties are significantly improved compared to the prototypical [Fe(tpy)2]2+ complex. In particular, the metal-to-ligand absorption extends into the near-IR and the 3MLCT lifetime increases by 5.5, whereas the metal-centered excited triplet state is very short-lived.

And the article was published in Advanced Functional Materials in 2019. Application In Synthesis of Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

Hole-transporting materials (HTMs) play a significant role in hole transport and extraction for perovskite solar cells (PeSCs). As an important type of HTMs, the spiro-architecture-based material is widely used as small organic HTM in PeSCs with good photovoltaic performances. The skeletal modification of spiro-based HTMs is a critical way of modifying energy level and hole mobility. Thus, many spiro alternatives are developed to optimize the spiro-type HTMs. Herein, a novel carbazole-based single-spiro-HTM named SCZF-5 is designed and prepared for efficient PeSCs. In addition, another single-spiro HTM SAF-5 with reported 10-phenyl-10H-spiro[acridine-9,9′-fluorene] (SAF) core is also synthesized for comparison. Through varying from SAF core to SCZF core as well as comparing with the classic 9,9′-spiro-bifluorene, it is found that the new HTM SCZF-5 exhibits more impressive power conversion efficiency (PCE) of 20.10% than SAF-5 (13.93%) and the com. HTM spiro-OMeTAD (19.11%). On the other hand, the SCZF-5-based device also has better durability in lifetime testing, indicating the newly designed SCZF by integrating carbazole into the spiro concept has good potential for developing effective HTMs. In the experiment, the researchers used Bis(4-methoxyphenyl)amine(cas: 101-70-2Application In Synthesis of Bis(4-methoxyphenyl)amine)
