标题:Methods of polymerization with aromatic thiol initiators
发明人：BOWMAN CHRISTOPHER N; LOVE DILLON
权利人:UNIV COLORADO REGENTS
摘要:Provided herein are methods of using aryl thiols as photoinitiators. The thiol compounds are useful as oxygen insen-sitive photoinitiators for applications such as bulk polymerizations and for specialty polymer synthesis by preparing aromatic thiol functionalized macroinitiators.

标 题 :Photochromic indeno-fused naphthopyrans
发明人：CHOPRA ANU
权利人:TRANSITIONS OPTICAL INC
摘要:Photochromic materials comprising indeno-fused naphthopyrans having substituents comprising a 4-fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fused naphthopyran are disclosed. The photochromic materials may exhibit faster fade rates as compared to similar indeno-fused naphthopyrans without a 4-fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fused naphthopyran. Substituted 2-propyn-1-ols utilized for the synthesis of the indeno-fused naphthopyrans disclosed herein are disclosed. Photochromic compositions and articles, such as optical elements, incorporating the photochromic materials disclosed herein are also disclosed.

摘要:Photochromic tetrahydroindolizines (THIs) bearing dihydroisoquinoline derivatives as heterocyclic bases and central fluorene groups have been synthesized via different chemical and photochemical pathways. Three alternative pathways for the synthesis of the target photochromic THI-based pyridazinopyrrolo[1,2-b]isoquinolines via in situ trapping with hydrazine hydrate are also provided. High product yields are obtained using different Sonogashira-mediated coupling reactions provided herein. Low temperature multichannel UV-vis and flash photolysis techniques were used to detect the photochromic and kinetic properties of the synthesized system.

权利人:AGENCY SCIENCE TECH & RES
摘要:There is disclosed an imprinted polymer support for solid phase organic synthesis (SPOS). The polymer support being obtainable from a method that comprises providing a substrate and a mold, the mold having a defined surface pattern. A composition is placed between the defined surface pattern of the mold and the substrate. The composition comprises a polymerisation medium with at least one functional monomer and a free radical initiator. The composition is polymerised to form an array of polymer imprints adhered to the substrate.
