▎ 摘 要
An ultrasonic method (20 kHz) is introduced to activate pristine ibuprofen organic molecular crystals via complexation with silver in nitrogen-doped oxidized graphene nanoplatforms (similar to 50 nm). Ultra-sonic complexation occurs in a single-step procedure through the binding of the carboxylic groups with Ag and H-bond formation, involving noncovalent pi C=C -> pi C=C* transitions in the altered phenyl ring and pi PY -> pi CO* in ibuprofen occurring between the phenyl ring and C-O bonds as a result of interaction with hydroxyl radicals. The ibuprofen-silver complex in << NrGO >> exhibits a similar to 42 times higher acceleration rate than free ibuprofen of the charge transfer between hexacyanoferrate and thiosulfate ions. The increased acceleration rate can be caused by electron injection/ejection at the interface of the << Ag-NrGO >> nanoplatform and formation of intermediate species (Fe(CN)5(CNSO3)x- with x = 4 or 5 and AgHS2O3) at the excess of produced H+ ions. Important for microwave chemotherapy, ibuprofen-silver complexes in the << NrGO >> nanoplatform can produce H+ ions at similar to 12.5 times higher rate at the applied voltage range from 0.53 to 0.60 V. << Ibu-Ag-NrGO >> NPs develop similar to 105 order higher changes of the electric field strength intensity than free ibuprofen in the microwave absorption range of 100-1000 MHz as revealed from the theoretical modeling of a cervix tumor tissue.
