Photochromic Cotton Fabric Prepared by Spiropyran-ternimated Water Polyurethane Coating

Photochromic materials have drawn growing interesting due to their capability of interconversion under the action of external optical stimulation, allowing diverse potential applications. Herein, we proposed a novel method of preparing photochromic cotton fabric coated by combined l-(2-hydroxyethyl)-3,3-dimethyl-6-nitrospiro [l(2H)-benzopyran-2,2-indoline] terminated waterborne polyurethane. The synthesized photochromic compounds 1-(2-hydroxyethyl)-3,3-dimethyl-6-nitrospiro[1(2H)-benzopyran-2,2-indoline] (SP-OH), were characterized by FTIR spectra, H-1 NMR and ultraviolet (UV) spectrum. The as-prepared spiropyran-terminated water polyurethane (SP-OH/WPU) was characterized via FTIR spectra, ultraviolet (UV) spectrum, SEM and size analysis. The photochromic cotton fabric was featured via FTIR spectra, ultraviolet (UV) spectrum and SEM. In addition, the photochromic properties, thermal stability of as-prepared cotton fabric was tested. The results showed that the photochromic compounds and SP-OH/WPU have been successfully synthesized and the resultant cotton fabric possesses excellent and durable photochromic properties, including noticeable and quick color alteration under UV radiation and fast recovery when exposed to green light. Furthermore, the excellent thermal stability ensured it undergo harsh service environment, which indicated that it is a good candidate for photochromic textile.

Structure Activity Relationship of 4-Phenyl-1-(1-Acylindolin-5-Ylsulfonyl)Pyrrolidin-2-Ones on Anticancer Activity

Microtubules play a dynamic role during cell division. In our early studies 4-phenyl-1-(1-acylindoline-5-sulfonylimidazolones were thoroughly explored and found that the indoline bicyclic system next to the sulfonyl group is very important for cytotoxicity. In this research, imidazolone motif was replaced with pyrrolidin-2-one and this isosteric replacement led to show some promising activity. Thus, the structure activity relationship of 4-phenyl-1-(1-acylindolin-5-ylsulfonyl)pyrrolidin-2-ones with the various acyl group at the indoline NH was explored. The presence of benzoyl groups with electron donating group was the more favorable for cytotoxicity while less bulky alkanoyl groups led to decrease cytotoxicity.

Gold(I)-Catalyzed Cascade Cyclization of Anilines with Diynes: Controllable Formation of Eight-Membered Ring-Fused Indoles and Propellane-Type Indolines

Heterocycle-fused indoles or indolines are distributed widely in a variety of natural products, bioactive agents, and pharmaceuticals. Herein, we describe the development of gold catalyzed cascade reactions of anilines with diynes to form eight-membered ring-fused indoles and propellane-type indolines, both of which proceed through an intramolecular 5-endo-dig hydroamination followed by an 8-endo-dig cycloisomerization. Controllable formation of eight-membered ring-fused indoles and propellane-type indolines was achieved through selection of the ligands and/or solvents. Protic solvents such as alcohols or IPr ligand favored the formation of eight-membered ring-fused indoles, whereas the use of Buchwald’s type ligands and/or nonpolar solvents gave propellane-type indoline predominantly. This reaction provides rapid access to two types of fused nitrogen heterocycles from simple aniline derivatives.

Interface Modification and Exceptionally Fast Regeneration in Copper Mediated Solar Cells Sensitized with Indoline Dyes

The photovoltaic performance of solar cells sensitized with indoline D205 dye and its new derivative comprising an alkoxysilyl anchoring unit (D205Si) in the [Cu(tmby)(2)](TFSI)(2/1) (tmby = 4,4′,6,6′-tetramethyl-2,2′-bipyridine, TFSI = bis(trifluoromethane)sulfonimide) redox couple mediated systems was studied in the presence of various titania/dye/electrolyte interface modifications. Cucurbit[7]uril (CB7) was employed to encapsulate dye molecules, creating an electronically insulating layer, suppressing electron interception by redox mediator, and leading to the increase in the electron lifetime in the titania conduction band. For example, the electron lifetime increased from 2.2 to 6.5 ms upon CB7 encapsulation of D205 cells at 0.9 V voltage. Further, molecular multicapping was optimized to minimize dye desorption and prevent electron recombination. As a result, photovoltaic performance was found to be enhanced by the interface modifications in most cases, especially when applied to the alkoxysilyl anchoring derivative. The charge transfer processes (dye regeneration, titania-dye and titania-redox mediator recombination) in the above-mentioned system and in the reference [Co(bpy)(3)](TFSI)(3/2) (bpy = 2,2′-bipyridine) redox couple mediated systems were investigated by means of small light perturbation electron lifetime measurements, electrochemical impedance spectroscopy, and nanosecond and femtosecond transient absorption spectroscopies. Indoline dyes were also found to be outstandingly fast regenerated by the Cu-based mediator (time constant shorter than 100 ns), which may open new opportunities for sensitizer improvements.

Synthesis and antioxidant screening of new 2-cyano-3-(1,3-diphenyl-1H-pyrazol-4-yl)acryloyl amide derivatives and some pyrazole-based heterocycles

The high functionality compound namely 2-cyano-3-(1,3-diphenyl-1H-pyrazol-4-yl)acryloyl chloride (1) was utilized as a building block synthon via reactions with some nitrogen and sulfur nucleophilic reagents. The present work was planned to study the effect of 2-cyano group on the reactivity and stability of C-2-C-3 double bond toward different strong-to-weak nucleophiles, in addition to its facility of nucleophilic addition at C-2-C-3 double bond to construct new heterocyclic derivatives. The proclivity toward some mono-, 1,2-, 1,3-, 1,4-, and 1,5-binucleophiles was investigated. The reaction with 2-cyanoacetohydrazide was mainly dependent on the reaction conditions. Some new heterocycles integrated with pyrazole scaffold were successfully synthesized, such as benzoxazinone, indoline, isoindoline, pyrazolone, chromene, and pyrimidopyrimidine derivatives. Some of the newly synthesized compounds were screened for their antioxidant activity using ABTS method, and the results revealed that some compounds exhibited promising inhibitory antioxidant activity.
