This communication reports a new type of supramolecular cyclodextrin-guest complexes using cyclodextrin coated upconversion nanoparticles as hosts and monovalent and divalent azobenzenes and arylazopyrazoles as guests. A potentially biocompatible photocontrol of the interaction by isomerization of the azobenzene or arylazopyrazole was achieved by laser irradiation at 980 nm and a very low light intensity of 0.22 W cm-2

-
Paragraph 0139; 0140, (2017/09/08)
Compositions and curing agents comprising a benzylated Mannich base composition. The benzylated Mannich base composition includes a reaction product of (a) a substituted phenolic compound having at least one substituent of formula (I): wherein R1 is each independently a linear or branched alkyl group having 1 to 4 carbon atoms, and R2 is hydrogen, methyl, ethyl or phenyl, with (b) a benzylated polyalkylene polyamine (II): wherein RA is substituted or unsubstituted benzyl; RB is each independently RA, or a hydrogen atom, or a group selected from C1-C16 linear, cyclic, and branched alkyl, alkenyl, and alkaryl groups; X, Y, and Z are independently selected from C2-C10 alkylene, and cycloalkylene groups; y is an integer from 0 to 7, and z is an integer from 0 to 4; and, optionally, (c) a multifunctional amine. Amine-epoxy compositions and articles produced from these compositions are also disclosed.

The bis-aminals obtained by tetraamine and phenylglyoxal condensation display various behaviours such as equilibrium between different configurations, rearrangements that lead to lactam derivatives, or amine deprotection. Our investigations about them were focused on three different linear amines, and then extended to polyazacycloalkanes cyclen and cyclam. Cyclam was also synthesised with the bis-aminals issued from condensation of linear polyamines with phenylglyoxal. The lactam derivatives described here were moreover, employed for the mono-N-functionalisation of tetraamines by phenyl-acetic acid group.
