摘要:含发色团的淬灭剂2和3能够通过折射率(ri)和紫外检测的凝胶渗透色谱(gpc)定量定量活性部位计数并确定活性催化剂聚合基团的质量分布,从而通过(ebi)催化1-己烯的聚合反应zrme 2 / B(c 6 F 5)3.通过动力学模型分析了催化剂形态数据的时间演变以及单体消耗,端基生成和本体分子量分布数据的时间分布,以确定通过将己烯插入zr-Me键引发的速率常数(k I),传播(k P),链转移形成亚乙烯基(k 1,2)和亚乙烯基(k 2,1)端基,并从zr-h键(k R)重新引发.与以前的模型假定快速重新启动催化剂不同,该分析表明k R比k P慢得多.催化剂形态数据对于进行这种区分至关重要.这项研究表明,使用2和3对生色团进行淬灭标记可以使用带有uv和ri检测器的gpc快速,定量地分析催化烯烃聚合反应的详细动力学模型.

标 题:Synthesis of oligonucleotide arrays using photocleavable protecting groups
发明人：MCGALL GLENN H; NAM NGO QUOC
权利人:AFFYMETRIX INC
摘要:Novel compounds are provided which are useful as linking groups in chemical synthesis, preferably in the solid phase synthesis of oligonucleotides and polypeptides. These compounds are generally photolabile and comprise protecting groups which can be removed by photolysis to unmask a reactive group. The protecting group has the general formula Ar-C(R1)(R2)-O-C(O)- wherein: Ar is an optionally substituted fused polycyclic aryl or heteroaromatic group or a vinylogous derivative thereof; R1 and R2 are independently H, optionally substituted alkyl, alkenyl or alkynyl, optionally substituted aryl or optionally substituted heteroaromatic, or a vinylogous derivative of the foregoing; and X is a leaving group, a chemical fragment linked to Ar-C(R1)(R2)-O-C(O)- via a heteroatom, or a solid support; provided that when Ar is 1-pyrenyl and R1=R2=H, X is not linked to Ar-C(R1)(R2)-O-C(O)- via a nitrogen atom. Preferred embodiments are those in which Ar is a fused polycyclic aromatic hydrocarbon and in which the substituents on Ar, R1 and R2 are electron donating groups. A particularly preferred protecting group is the 'PYMOC' protecting group, pyrenylmethyloxycarbonyl, where Ar=pyrenyl and R1=R2=H. Also provided is a method of forming, from component molecules, a plurality of compounds on a support, each compound occupying a separate predefined region of the support, using the protected compounds described above.
