Dimethyl sulfoxide (DMSO) is known as a green solvent (organosulfur) for inorganic/organic materials having a high dielectric constant and high resistance to redox reactions. Due to very low toxicity,
In high dielectric constant medium (DMSO d6) only a well-resolved doublet is obtained indicating An interesting feature of the data in Table I1 is that in solvents of low dielectric constant ScH, > 6.
Characterizing Cycloaliphatic-containing Polyimides – With R= CBDA-6FDA / H-PMDA-6FDA the T homo remained unchanged even when sublimed N700 was used The traditional PAA procedure was used and it was found that t-CHDA is dissolved in NMP, DMAc, DMF, DMSO.
