Synthesis and Structure-Activity Relationship of <i>N</i>-Substituted Carbazole Oxime Ester Photoinitiators
نویسندگان
چکیده
Four N-phenyl substituted carbazole oxime ester photoinitiators were synthesized and their structure-activity relationship systematically investigated. These have a broad absorption in the range of 300-400 nm tail extends above 400 nm. Under 405 LED light irradiation, esters undergo photodecarboxylation generate active free radicals to induce polymerization acrylates. The tert-butyl aldehyde-oxime Ph-N-CZ-2 with terminal methyl group exhibit best photoinitiation performance among four N-substituted esters.

متن کاملSynthesis and antitumor activity of novel N-substituted carbazole imidazolium salt derivatives
A series of novel N-substituted carbazole imidazolium salt derivatives has been prepared and investigated for their cytotoxic activity against five human tumor cell lines by MTS assay. The results indicated that the existence of 5,6-dimethyl-benzimidazole ring, substitution of the imidazolyl-3-position with a 2-bromobenzyl or naphthylacyl group, as well as alkyl chain length between carbazole a...

Some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. Reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (SNAr). The structures of these co...
