  Synthesis of (NH)_m(NMe)_4−m-Bridged Calix[4]pyridines and the Effect of NH Bridge on Structure and Properties

  摘要：

  The (NH)(m)(NMe)(4-m)-bridged calix[4]pyridines (m = 1-4) 19-23 were synthesized in excellent yields from deprotection of N-allyl groups of (NAllyl)(m)(NMe)(4-m)-bridged calix[4]pyridine derivatives 8 and 15-18, which were prepared in moderate yields by macrocyclic 2+2 and 1+3 coupling reactions between simple diamino- and dibromo-substituted fragments, In the solid state, (NH)(m)(NMe)(4-m)-bridged calix[4]pyridines adopted different 1,3-alternate conformations due to mainly the formation of varied conjugation systems of bridging NH units with their neighboring pyridines. In solution, all (NH)(m)(NMe)(4-m)-bridged calix[4]pyridines were very fluxional and the rates of interconversion of various conformational structures were very rapid relative to the NMR time scale, While (NH)(4)-bridged calix[4]pyridine 23 formed the strongest conjugation system, (NH)(2)(NMe)(2)-bridged calix[4]pyridine 21 acted as a selective fluorescence probe in the recognition of zinc(II) ion in solution with the dramatic enhancement of fluorescence intensity.
