Abstract
This work is dedicated to low-molecular hydrogels based on biodegradable sodium deoxycholate (SDC) and lysine hydrochloride (lys × HCl) with magnesium octa-[(4'-benzo-15-crown-5)-oxy]phthalocyaninate (Mgcr8Pc) as the active component, namely, their synthesis, spectral properties of gel-solubilized Mgcr8Pc, its release from the gel etc. Addition of Mgcr8Pc occurs both via the mixing of the components and via its diffusion from the aqueous solution into the phase of the formed SDC/lys × HCl gel. Mgcr8Pc-containing hydrogels are thermoreversible. The state of Mgcr8Pc in the SDC/lys × HCl/NaCl gel at the room temperature and in the melt is studied using spectral methods. Gel melting releases Mgcr8Pc in the form of a micelle-bound monomer. The presence of the Mgcr8Pc monomer phase in the phthalocyanine-carrying supramolecular hydrogel causes fluorescent activity of the latter.
