摘要:Supramolecular silicone elastomers were first prepared via the self-assembly of nucleobase-functionalized polysiloxanes which were synthesized by a catalyst-free aza-Michael reaction. The nucleobases adenine (A) and thymine (T) form A-A, T-T, and A-T hydrogen bonding via base pair recognition. The mechanical properties of the elastomers improved a lot after the process and can be controlled by adjusting the A and/or T content. These elastomers emit blue light under UV light irradiation because of the unconventional Si-N coordination bond and they exhibit ultra-low temperature (-114.53 degrees C) resistance because the normal crystallization disappears at -60 degrees C.
