How about DMSO (bp 189 C) or water (bp 100C)?

Xavier Guillory

Unfortunately, Amino-POSS seems unstable in water (http://pubs.acs.org/doi/abs/10.1021/acs.jpcb.5b01955)

By the way, are you talking about amino-POSS with 8 amine functions per molecule?

Or only one amine funtion and seven alkyl functions like this one : http://www.sigmaaldrich.com/catalog/product/aldrich/560294?lang=fr®ion=FR

What solvent did you try already?

Best regards

Mateusz Janeta

Octa amino-POSS is stable onyly in diluted methanol solution.
