[2] The invention provides for new polymer compounds and methods for the preparation of modular narrow band gap conjugated compounds and polymers that incorporate exocyclic cross-conjugated donors or substituents, as well as novel monomer components of such polymers and the resulting products which comprise materials and useful electronic devices with novel functionality. This methodology is being reported for the first time. Two organo-soluble polyimide resins containing phenyl-substituted quinoxaline units (PIPQ) were successfully prepared via the two-step chemical imidization procedure from an aromatic diamine, 6(7 . For this, a series of 13 new spiropyrrolidine derivatives were designed, synthesized, characterized and evaluated for their in vitro antimicrobial, antioxidant and antidiabetic potential. Soluble in: alcohol : water, 6850 mg/L @ 25 C (est) water, 6.60E+05 mg/L @ 25 C (exp) . Home; About us; . Soluble to 100 mM in DMSO Except where otherwise noted, . Abstract. Solubility determination of poorly water-soluble drugs is pivotal for formulation scientists when they want to develop a liquid formulation. A water-soluble photosensitizer, PQs-PEG5, based on a novel pyrazino[2,3-g]quinoxaline (PQ) prototype compound (PQs-5), was designed and synthesized. Formula. The journal publishes majorly in the area(s): Adsorption & Catalysis. Yang's group reported two multifunctional emitters based on quinoxaline with simultaneous polymorph-dependent TADF, AIE, and multi-color MCL features . IF ON SKIN: Wash with plenty of soap and water. Contact. Different physicochemical parameters namely thickness, solubility in water, water vapour transmission rate of the films prepared from native and modified starches were carried out.
