In recent years, ultrasound-assisted PDT applications have begun to be investigated in phthalocyanine and BODIPY derivative compounds. BODIPY compounds stand out with their adjustable photophysical and photochemical properties, chemical purity, and singlet oxygen generation capacity. Enhancing singlet oxygen production by BODIPY through the application of ultrasound appears to be a promising avenue for advancing this treatment method. In this context, exploring the potential of sonophotochemical properties is of particular interest. The limited SPDT applications of BODIPY derivative compounds increase the importance of investigating the sonophotochemical properties of the compounds. Therefore, a new water-soluble distyryl-type BODIPY fluorophore having phenyl ring substituted with a 4-dibenzothienyl group at <i>meso</i>-position and iodines as heavy atom at 2- and 6-positions has been synthesized successfully. The singlet oxygen production capacities of all intermediates and target product were evaluated by both photochemically and sonophotochemically.

However, the highly selective synthesis of these two compounds, and particularly of glutaraldehyde, is challenging. To improve the reaction rate and product selectivity of cyclopentene oxidation using green hydrogen peroxide (H₂O₂, 30 wt%) as an oxidant, activated carbon (AC)-supported amphiphilic vanadium-doped heteropolyacid (HPA) catalysts (AC-COIMI-C_n-HPA) were prepared by a series of modifications of AC, including acidification, imidazolylation, ammonium saltification, and HPAs loading. The structures and physicochemical properties of the catalysts were characterized by Fourier infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and nitrogen adsorption–desorption. The developed catalyst exhibits excellent catalytic properties and high selectivity toward glutaraldehyde. The AC carrier increases the number of effective active sites on the catalyst. The amphiphilicity of the catalyst increased the reaction rate. Vanadium doping of HPA enables fine-tuning of the oxidizability of the catalyst. The effects of the different active components of the catalyst, alkyl groups on the imidazole ring, solvent type and dosage, HPA loading on the catalyst, catalyst dosage, oxidant dosage, reaction temperature, and reaction time on the oxidation of cyclopentene were comprehensively examined. Finally, the optimized conditions were determined as follows: HPA doping by four V atoms (PW₈V₄), octyl (C₈) linked to the imidazole, 1 mL of acetonitrile, HPA loading of 35 wt%, 500 mg of the catalyst (AC-COIMI-C₈–35%PW₈V₄), n(H₂O₂):n (cyclopentene) = 2, reaction temperature and time of 40°C and 6 h, respectively.
