  摘要：

  带有 4-(benzothiazol-2-yl)-3-hydroxyphenyl 及其 4-(benzimidazol-2-yl) 类似物的四种双环二氧杂环丁烷的未催化热分解有效地引起了由于 ESIPT（激发态分子内质子转移）引起的热化学发光 (TCL)无论是在溶液中还是在固态中。TCL 的效率 (Φ TCL ) 在固态比在溶液中高约 15 倍。这种固态的高 Φ TCL 被认为是 TCL 几乎没有经历任何聚集引起的淬火的结果，因为基于发射体的 ESIPT 的大斯托克斯位移，并且因为 TCL 通过温度淬火减少很少，与解决方案中的案例。单线态化学激发效率 (Φ S) 似乎增加，达到峰值，然后随着反应温度的升高而降低。

  Synthesis of Bicyclic Dioxetanes Bearing a 4-(Benzimidazol-2-yl)-3-hydroxyphenyl Group and Their Base-Induced Chemiluminescent Decomposition in an Aprotic Medium and in an Aqueous Medium

  摘要：

  Bicyclic dioxetane, 5-tert-butyl-4,4-dimethyl-2,6,7-trioxabicyclo[3.2.0]heptane, bearing a 4-(benzimidazol-2-yl)-3-hydroxyphenyl group at the 1-position and its N-substituted benzimidazolyl-analogs were synthesized. N-Methylbenzimidazolyl-analog and N-phenylbenzimidazolyl-analog were found to undergo charge-transfer-induced decomposition (CTID) to effectively give light in both TBAF/MeCN and in NaOH/H2O. The CTID of N-(4-carboxybutyl)benzimidazolyl-analog gave also effectively light both in MeCN and in H2O. On the other hand, chemiluminescent CTID of the unsubstituted benzimidazolyl-analog changed depending on the base used: TBAF/MeCN induced weak emission of yellow light due to a dianion of the dioxetane, while TMG(tetramethylguanidine)/MeCN induced strong emission of blue light due to a monoanion of the dioxetane.

  Chemiluminescent decomposition of dioxetanes bearing a 3-oxidophenyl was investigated in various solvents. The solvent-dependency of chemiluminescence efficiency ΦCL showed a hierarchy that could be stratified into three classes: ΦCL in aprotic polar solvents » in alcohols » in water. Hydrogen bond donor ability of the solvent was mainly responsible to the hierarchy. Singlet-chemiexcitation efficiency
