A redox-active, tetradentate ligand, N,N'-bis-(3-dimethylamino-propyl)-4,5-dimethoxy-benzene-1,2-diamide ([N(2)N(2)(cat)](2-)), was developed, and the six-coordinate metal complexes [N(2)N(2)(cat)]TiCl(2) (3) and [N(2)N(2)(cat)]ZrCl(2) (4) were synthesized. The tetradentate ligand was determined to be fluxional in 3 and 4, enabled by reversible dissociation of the neutral amine groups of the [N...

A number of cyclopentadienyltitanium aryloxide complexes, 1-Ar-2,3,4,5-Me(4)-Cp(2,6-(i)Pr(2)C(6)H(3)O)TiCl(2) (Ar = 4-Me(3)SiPhenyl (5), 4-(i)PrPhenyl (6), 4-MePhenyl (7), 3,5-(CF(3))(2)Phenyl (8)) and (1-Ar-2,3,4,5-Me(4)CpTiCl(2))(2)(OAr'O) (Ar' = 4,4'-(3,3',5,5'-(i)Pr(4)C(6)H(2)-C(6)H(2)), Ar = 4-SiMe(3)Phenyl (9), 4-MePhenyl (10)) were synthesized from the reaction of a corresponding cyclope...

Purpose: To investigate the causes of Implantable Collamer Lens (ICL) explantation and study the visual outcomes after further management in a retrospective case series. Methods: Retrospective chart review was performed for all the eyes that underwent bilateral or unilateral ICL explantation between March 2010 and April 2015. Incidence & causes of explantation, time between primary & secondary ...
