5.A method according to claim 1, in which the poor solvent is added at an amount of 20 to 200% by weight to the total weight of the solid host compound and the solid or liquid guest compound prior to mixing and/or kneading in Step (b). 6.A method according to claim 1, in which...
Five crystalline organic acid-base salts [(HL)(dnsa(-)), L=2,6-dimethylaniline, dnsa(-) = 3,5-dinitrosalicylate] (1), [(HL+)(4-Hnpta(-)), 4-Hnpta(-) = 4-nitrophthalate] (2), [(HL)(2)(nds)(H2O)(2), nds=1,5-naphthalenedisulfonate] (3), [(HL)(dnb)(Hdnb), dnb=3...
poly(2‐vinyl pyridine)High molecular weight polyoxyethylene (PEO) was synthesized by using a quaternary catalyst composed of triisobutyl aluminum, phosphoric acid, water, and N , N -dimethylaniline (DMA). Optimum synthesis conditions and some properties of the product were studied. This catalyst ...

nitrosodimethylaniline (RNO)/imidazole technique monitored the singlet oxygen formation. BRJ and betanin decreased the RNO absorbance at 440 nm by 12% and 9% after 45 min of irradiation, respectively. Furthermore, betanin interaction with Bcl-2 proteins was examined using binding free energy ...
of each dyad or regioregularity, whose values ranged from 38% to 95% with this molecule, were analysed using common NMR spectroscopic data. Additionally, the synthesis of a new cationic polyelectrolyte, poly{1,4-(2/3-aminobenzene)-co-alt-2,7-[9,9´-bis(6’’-N,N,N-trimethylammonium...
