Abstract Two novel and well-defined polyhedral oligomeric silsesquioxanes (POSS) with two same Si8O12 cores and a reactive NH group, namely bridged-POSS (2a and 2b), have been prepared by the traditional ‘corner-capping’ reaction. X-ray diffraction demonstrates that those two POSS have the similar T8 structure. From the thermo-gravimetric analysis, bridged-POSS shows the better thermal degradation stability than the contrastive POSS.
