中文摘要:
我们准备了偶氮苯 PNA 单位和由典型 t Boc 方法。包含一个偶氮苯单位(N-PNA ) 的偶氮苯 PNA 单位和 PNA 与紫外、可见的轻照耀显示出可逆相片异构化。有互补 DNA 的 N-PNA 的杂交导致了偶氮苯的相片异构化率常数的可观的减少。
英文摘要:
We prepared the azobenzene PNA unit and synthesized various PNAs containing an azobenzene unit by a typical tBoc method. Both the azobenzene PNA unit and PNA containing an azobenzene unit (N-PNA) showed reversible photoisomerization with UV and visible light irradiation. The hybridization of N-PNA with complementary DNA resulted in a considerable decrease of the photoisomerization rate constant of the azobenzene.
