An ensemble sensor system that exhibited selective luminescence enhancement upon binding to thymidine 5'-triphosphate (TTP) in HEPES buffer over other nucleotides was developed. The ensemble system consisted of an energy acceptor (FIrpic-bis(Zn2+-dipicolylamine conjugate, FIrpic=bis[(4,6-difluorophenyl)-pyridinato-N,C2+]picolinate) derivative) and an energy donor (mCP-Zn2+-cyclen, mCP=N,N'-dicarbazolyl-3
开发了一种集合传感器系统,该系统在与HEPES缓冲液中的胸苷5'-三磷酸(TTP)结合后比其他核苷酸具有选择性的发光增强。该集合系统由能量受体(FIrpic-双(Zn2 +-二甲基吡啶胺共轭物,FIrpic =双[(4,6-二氟苯基)-吡啶基-N,C2 +]吡啶甲酸)衍生物)和能量供体(mCP-Zn2 +-环,mCP = N,N′-二咔唑基-3,5-苯)。在这些核苷酸中,TTP的选择性识别和发光增强是通过胸腺嘧啶单元与Zn2 +-环素(周期数= 1,4,7,10-四氮杂环十二烷)的牢固结合以及mCP和FIrpic部分之间的分子间能量转移而实现的。
