Photoinitiated Polymerization with Visible Lasers

9526755脖子PI的计划专注于激光引发的光聚合和由此实现的技术。这项工作的总体目标是了解复杂过程的所有步骤，从最初由光引发剂和共引发剂形成的激发态的光吸收和处置，到导致固体光聚合物的反应链。目前的计划是开发能够在更长波长(600 nm，重点是在670 nm处工作的系统)的最佳光速下使用的光化学。开发可溶于硅丙烯酸酯和碳氟丙烯酸酯单体的引发剂体系。了解光聚合中形成的交联型聚合物的结构，并将其与光引发剂化学/光物理联系起来。继续非含氧硅烷单体的合成研究，开发从硅烷单体和预聚体形成固体光聚合物的光方法，并从事在非丙烯酸酯、硅烷单体体系中起作用的引发剂的合成/开发。这项研究将有助于通过开发新的光敏抗蚀剂材料和催化剂为下一代微电子电路的制造奠定基础。***

9526755 Neckers The PI's program focuses on laser initiated photopolymerization and technologies thereby enabled. The overall goal of the work is to understand all steps of the complex processes from the light absorption and disposition of the excited states formed initially from photoinitiators and coinitiators through the chain of reactions leading to solid photopolymer. The immediate plans are to develop photochemistries which can be used at optimal photospeeds at longer wavelengths (600 nm with emphasis on systems which function at 670 nm). To develop initiator systems soluble in silicon acrylate and fluorocarbon acrylate monomers. To understand the structures of the crosslinked polymers formed in photopolymerizations and to relate this to photoinitiator chemistry/photophysics. To continue synthetic studies in non-oxygen containing silane monomers, to develop photomethods for forming solid photopolymers from silane monomers and prepolymers; and to engage in the synthesis/development of initiators which function in non- acrylate, silane monomer systems. %%% This research should aid in laying the foundation for manufacturing of next-generation microelectronic circuits through development of new photosensitive resist materials and catalysts. ***
