A new functionalized fullerene derivative, [60]fullerene-poly(3-azidomethyl-3-methyl oxetane) (C60-PAMMO), was synthesized for the first time using a modified Bingel reaction with [60]fullerene (C60) and bromomalonic acid poly(3-azidomethyl-3-methyl oxetane) ester (BM-PAMMO). The product was characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis), and nuclear magnetic resonance (NMR) spectroscopy analyses. The results confirmed the successful preparation of C60-PAMMO. Moreover, the thermal decomposition of C60-PAMMO was analyzed by differential scanning calorimetry (DSC), thermogravimetric analysis coupled with infrared spectroscopy (TG-IR), and in situ FTIR spectroscopy. The decomposition of C60-PAMMO showed a three-step thermal process. The first step at approximately 150 °C was related to the cycloaddition of the azido groups (-N3) with [60]fullerene. The second step was ascribed to the decomposition of the remaining PAMMO main chain at approximately 320 °C. The final step was attributed to the burning decomposition of amorphous carbon, the main chain, N-heterocyclic components and the carbon cage around 510 °C.
A bifunctional dimethylsulfoxide substitute enhances the aqueous solubility of small organic molecules

, p. 269 - 277 (2012)
An oxetane-substituted sulfoxide has demonstrated potential as a dimethylsulfoxide substitute for enhancing the dissolution of organic compounds with poor aqueous solubilities. This sulfoxide may find utility in applications of library storage and biological assays. For the model compounds studied, significant solubility enhancements were observed using the sulfoxide as a cosolvent in aqueous media. Brine shrimp, breast cancer (MDA-MB-231), and liver cell line (HepG2) toxicity data for the new additive are also presented, in addition to comparative IC50 values for a series of PKD1 inhibitors.
