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 °C) resistance because the normal crystallization disappears at −60 °C.

通过均组装和杂组装 制备超分子有机硅弹性体

超分子有机硅弹性体首先通过核碱基官能化的聚硅氧烷的自组装制备该聚硅氧烷是通过无催化剂的aza-Michael反应合成的。核碱基腺嘌呤(A)和胸腺嘧啶(T)通过碱基对识别形成A–A,T–T和A–T氢键。该方法后,弹性体的机械性能有了很大改善,可以通过调节A和/或T含量来控制。这些弹性体由于非常规的Si–N配位键而在紫外光照射下发出蓝光,并且由于在60°C时正常结晶消失,因此具有超低温(−114.53°C)耐性。
