  摘要：

  阳离子铑（I）配合物的[Rh（1,5-COD）2 ] A（A =光学传递函数，PF 6，1,5- COD = 1,5-环辛二烯）已被证明表现出过渡高催化活性金属介导的开环聚合的（ROP）硅桥联[1] ferrocenophanes（例如，fcSiMe 2（1A），FC =铁（η 5 -C 5 H ^ 4）2），以定量得到高分子量（中号n > 10 5）聚二茂铁基硅烷（例如[fcSiMe 2 ] n（2a））。然而，所得的聚二茂铁溶液长时间暴露于催化剂导致分子量显着下降。用[Rh（1,5-cod）2 ] OTf形成高分子量聚碳硅烷均聚物（7）（M n = 4.20×10 ），也证明过渡金属催化的四甲基二硅环环丁烷（6）的ROP以及该物质与1a的共聚是可行的。5到1.08×10 6，PDI = 1.39-2.08）和聚（carbosilane- ř -ferrocenylsilane）（8）共聚物（中号ñ

  network formation to occur. We also explored the tendency of the cylindrical seed micelles to form aggregates by the addition of PI-b-PFDMS (PI = polyisoprene) block copolymers (block ratios 6:1, 3.8:1, 2:1, or 1:1), and striking differences were noted. The results ranged from typical micelle elongation, as reported in previous work, at high corona to core-forming block ratios (PI-b-PFDMS; 6:1) to predominantly

  The organometallic-inorganic diblock copolymer poly(ferrocenyldimethylsilane-b-dimethylsiloxane) (PFDMS-b-PDMS) with a 1:6 block ratio unexpectedly forms:long rodlike micelles rather than spherical structures in a variety of PDMS-selective n-alkane solvents when the solutions are prepared:at. or near ambient; temperature. The cylindrical structures represent the thermodynamically preferred morphology and consist of an iron-rich PFDMS core and a corona of PDMS. The length of the micelles can be varied from 70 nm to 10 mum by altering the method of sample preparation. In addition; the dimensions of the micellar core can be controlled through variations in the length of the PFDMS block,which is achieved by altering the molecular weight of the diblock copolymer while maintaining a constant block ratio. In contrast, when micelles are formed above the T-m of PFDMS (ca. 120-145 degreesC), spherical aggregates are formed, which suggests that crystallization of the core polymer is the driving force for the formation; of wormlike micelles below T-m,. Furthermore, the analogues with amorphous polyferrocene blocks, poly(ferrocenylmethylphenylsilane-b-dimethylsiloxane) (PFMPS-b-PDMS) and poly(ferrocenylmethylethylsilane-b-dimethylsiloxane) (PFMES-b-PDMS), form spherical micelles in hexane at room temperature. This lends further support to the proposition that the crystalline nature of the PFDMS block plays a pivotal role in the unexpected formation of cylindrical micelles. To provide an application of this concept, an analogous PFDMS block copolymer With polyisoprene, PI-b-PFDMS, was prepared and, as predicted, was found to form cylindrical micelles in hexane.

  In depth studies of the use of electron transfer reactions as a means to control the self-assembly of diblock copolymers with an electroactive metalloblock are reported. Specifically, the redox-triggered self-assembly of a series of polystyrene-block-polyferrocenylsilane (PS-b-PFS) diblock copolymers in dichloromethane solution is described. In the case of the amorphous polystyrene(n)-b-poly(ferrocenylphenylmethylsilane)(m) diblock copolymers (PSn-b-PFMPSm: n = 548, m = 73; n = 71, m = 165; where n and m are the number-averaged degrees of polymerization), spherical micelles with an oxidized PFS core and a PS corona were formed upon oxidation of more than 50% of the ferrocenyl units by [N(C6H4Br-4)(3)][SbX6] (X = Cl, F). Analogous block copolymers containing a poly(ferrocenylethylmethylsilane) (PFEMS) metalloblock, which has a lower glass transition temperature, behaved similarly. However, in contrast, on replacement of the amorphous metallopolymer blocks by semicrystalline poly(ferrocenyldimethylsilane) (PFDMS) segments, a change in the observed morphology was detected with the formation of ribbon-like micelles upon oxidation of PS535-b-PFDMS103 above the same threshold value. Again the coronas consisted of fully solvated PS and the core consisted of partially to fully oxidized PFS associated with the counteranions. When oxidation was performed with [N(C6H4Br-4)(3)] [SbF6], reduction of the cores of the spherical or ribbon-like micelles with [Co(eta-C5Me5)(2)] enabled full recovery of the neutral chains and no significant chain scission was detected.
