  Spectral Luminescent Properties of 2-Aryl-5-(2,6-dimethoxyphenyl)-1H-1,3,4-oxadiazoles

  摘要：

  2-Aryl-5-(2,6-dimethoxyphenyl)-1H-1,3,4-oxadiazoles were synthesized by cyclization reaction of benzoylbenzohydrazides in SOCl2, and their spectral luminescent properties were studied. The oxadiazoles containing phenyl or o-methoxyphenyl substituents in the position 2 were shown to luminesce with a high quantum yield in polar and nonpolar solvents. The replacement of these substituents by 2-hydroxyphenyl group led to oxadiazole intensely emitting only in highly polar aprotic DMSO.

  The reaction of Mn(OAc)2·4H2O with 2,6-dimethoxybenzoylsalicylhydrazide (H3dmbshz) leads to a dodecanuclear manganese metallamacrocycle [Mn12(dmbshz)12(EtOH)6], 1. The successive manganese centers are connected by the hydrazide N–N groups of the ligands in an alternating pentadentate binding mode, hexadentate binding mode. The alternation results in two alternating chelation modes around the metal centers, a tridentate–tridentate chelation mode and a bidentate–tridentate chelation mode. The metal ions in 1 are in a ⋯(AAΔBCAΛB)(AAΔBCAΛB)⋯ chiral sequence, the alternation of the chiralities expanding the cyclic ring system to a 36-membered dodecanuclear manganese metallamacrocyclic ring system with S6 point group symmetry.

  Mn(OAc)2·4H2O与2,6-二甲氧基苯甲酰水杨酰肼（H3dmbshz）反应，生成十二核锰金属大环[Mn12(dmbshz)12(EtOH)6]，1。连续的锰中心通过配体的肼N-N基团以交替的五齿配位模式和六齿配位模式连接。这种交替作用在金属中心周围形成两种交替的螯合模式，即三齿-三齿螯合模式和二齿-三齿螯合模式。1中的金属离子呈⋯(AAΔBCAΛB)(AAΔBCAΛB)⋯手性序列，手性的交替将环状系统扩展为具有S6点群对称性的36元十二核锰金属大环系统。
