Stable crystalline complexes of Co(II) acetylacetonate [Co(II)(acac)2], trifluoacetylacetonate [Co(II)(tfac)2], and hexafluoroacetylacetonate [Co(II)(hfac)2] with triphenodioxazines (TPDO) were synthesized and their structures studied using X-ray crystallography. In the crystal, complexes [Co(II)(tfac)2]TPDO and...
A novel photoreversible photochromic system, 3-(2-benzylbenzoyl)-1,2-R,R(1)-4(1H)-quinolinones/12-hydroxy-5-R-5a-R(1)-6-phenyl-5a,6-dihydrobenzo[b]acridin-11(5H)-ones, is described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
