The dyad exhibits a panchromatic nature revealing both the phthalocyanine and pheophorbide derived bands in the UV-Vis absorption spectrum. The 1 H NMR spectroscopy data combined with theoretical calculations indicate the presence of spatial intramolecular interactions between the phthalocyanine, pheophorbide and spacer fragments of the dyad allowing to forecast its enhanced nonlinear optical properties, as well as the characteristic energy transfer from the excited pheophorbide subunit to the phthalocyanine core. Indeed, when excited in the UV-Vis range, the conjugate shows red fluorescence with the spectral maximum at 686 nm, which is close to the one of the initial zinc phthalocyaninate. Furthermore, the dyad effectively generates singlet oxygen and, in the presence of polyvinylpyrrolidone (PVP) as biocompatible solubilizer, forms stable micellar saline solutions with the particles ranged in size between 40 and 100 nm. These nanoparticles represent promising third-generation photosensitizing systems for application in theranostics. lowing equation: [44] S R S R toluene f where G is the integrated emission area, n is the refractive index of the solvent, A λ is the absorbance at the excited wavelength, and Φ f is the fluorescence quantum yield.

The aggregation characteristics of macrocycles in the aquatic environment (CAC, aggre-gate size, zeta potential) have been studied. It has been demonstrated that the resulting aggregates have the ability to solubilize the lipophilic azo dye Orange OT, and the solubilizing ability significantly increases on going from butyl to tetradecyl derivatives. Using the methods of dynamic and electrophoretic light scattering and fluorimetry with ethidium bromide as a probe, it was shown that the obtained macrocycles interact with the DNA of the calf thymus. It was found that the efficiency of the interaction is greatly influenced by the length of the oxyethyl fragments: macrocycles containing tetraethylene glycol fragments are more effective than triethylene glycol analogs, causing a 2-fold compaction of DNA.","PeriodicalId":18090,"journal":{"name":"Macroheterocycles","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71166826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
