Synthesis of polymeric and macrocyclic Lewis acids: influence of backbone on degree of aggregation.
نویسندگان
چکیده
A simple, one-step synthesis of multinuclear Lewis acids can be driven with high selectivity towards either macrocyclic or polymeric arrays by appropriate choice of backbone framework.

The 17-membered macrocyclic spermine alkaloid protoverbine (8-phenyl-1,5,9,13-tetra azacycloheptadecan-6-one) was isolated From the aerial part of verbascum speciosum. The natural polyamines are ubiquitous bases reported to have several important functions in animals, plants and microorganisms. They are involved in processes of transcription and translation in protein synthesis and influence gr...
متن کاملry of an ion - com plexat ion by macrocyclic multidentate Lewis acids
In contrast to the extraordinary achievements of cation complexation in host-guest chemistry, only recently has anion complexation by compounds containing electrondeficient atoms such as boron, mercury, tin and silicon received attention. We here present a new class of carborane-supported macrocyclic multidentate Lewis acid hosts which bind nucleophilic species to form isolable host-guest compl...

The influence of polymeric dispersants containing different functional groups on TiO2 pigment particle suspension was investigated at pH 6.0 and 9.5, using rheology and particle size data. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers modified with carboxylate and/or hydroxyl groups. The pigment suspension was strongly affected by both p...
