摘要:水溶性自组装超分子宿主分子在碱性溶液中催化原甲酸酯的水解.催化和未催化水解反应的速率常数的比较表明,原甲酸三正丙酯的速率加速度高达 3900.动力学分析表明,超分子主体的水解机理符合michaelis-Menten模型.包括 (13) C 标记实验在内的机理研究表明,催化系统的静止状态是封装在宿主中的中性底物.反应的 K Cat 步骤的激活参数表明,在组装中的底物封装后,与未催化反应相比,激活熵变得更负.此外,溶剂同位素效应显示正常的 K(H 2O)/ K(D 2O) = 1.6,确认在限速步骤中发生质子转移的 As E2 机制.这与未催化反应的 A1 机制相反,其中质子化底物的分解是限速的.

标题 :Synthesis of ruthenium or osmium metathesis catalysts

权利人:CALIFORNIA INST OF TECHN
摘要:The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are independently any anionic ligand; n L and L 1 are any neutral electron donor ligand; and, n R and R 1 are each hydrogen or one of the following substituent groups: C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl. Optionally, the substituent group may be substituted with one or more groups selected from C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted with one or more groups selected from a halogen, a C 1 -C 5 alkyl, or a C 1 -C 5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R 1 is —CHCR 12 R 13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.

标题 :A method for synthesis of metal halide perovskite (cspbbr3) nano/microcrystals
发明人：M A GOKUL; RAHMAN ATIKUR

摘要:The present invention relates to metal halide perovskite (CsPbBr3) nano/microcrystals. Specifically, the present invention relates to a method for the synthesis of metal halide perovskite (CsPbBr3) nano/microcrystals. The present invention uses an easy, scalable low temperature growth of metal halide nanoparticles like CsPbBr3. The method uses a clever play on the solubility and ion exchange mechanism to precipitate nano and microcrystals of metal halide perovskites. The synthesis resulted in stable perovskite crystals with high photo- luminescence, ultralow dark current and control over their morphology. The combination of ultralow dark current, high responsivity, exceptional detectivity, and broad-band photon detection capabilities makes these crystals an excellent choice for upcoming sensors and detector technologies.
