A 4-N-methylphthalimide/water wet cake (50.0 grams (g) dry weight, containing 10-60% water), resulting from either a mixed acid (H2SC /HNO3) nitration of N- methylphthalimide or an all nitric acid nitration of N-methylphthalimide, was charged to a 1000 mL, single-necked (24/40 joint) round-bottomed flask, equipped with a magnetic stir bar, and means to heat the flask with an external temperature controlled oil bath. The flask was then charged with 367 g of toluene, and enough additional deionized water was added such that the total amount of water present in the flask was equal to 160 g. The amount of water used targeted 20 to 25 wt% of 4NPI with respect to the total weight of 4NPI and water. The reaction mixture was magnetically stirred with an oil bath set temperature of 90C. After the 4NPI had dissolved in the toluene the stirring was stopped, and the lower water phase was removed via pipette. This method of dissolution and separation of the 4NPI toluene phase from the aqueous phase constitutes a purification of the 4NPI as water soluble impurities were extracted from the 4NPI/toluene phase into the aqueous phase. This dissolution/separation method is termed herein the “4NPI Extraction.” The 4NPI toluene solution was then placed on a roto-evaporator, equipped with a hot oil bath to heat the flask, and plumbed to a cold trap connected to a vacuum pump. The flask was rotated in the hot oil bath (temperature controlled at 110C) and the solvent was removed under reduced pressure (<30 mm). Once the majority of toluene had been removed, the flask was allowed to rotate in the oil bath at 110C, 25 mm, for 60 minutes, to afford a dry solid free of toluene and water. The solid was transferred to a glove box inerted with dry nitrogen. The desired dried catalyst (HEGC1, TBAB, or C6B) was added to the dried 4NPI for the bisimide forming reaction.

550-44-7, Name is 2-Methylisoindoline-1,3-dione, molecular formula is C9H7NO2, belongs to indolines-derivatives compound, is a common compound. In a patnet, author is Glinka, Adam, once mentioned the new application about 550-44-7, SDS of cas: 550-44-7.

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.

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.
