Stability and solid-state polymerization reactivity of imidazolyl- and benzimidazolyl-substituted diacetylenes: pivotal role of lattice water†
† Electronic supplementary information (ESI) available: Detailed description of the C-H···O and C-H···N hydrogen bonding interactions present in 1,6-bis(1-imidazolyl)-2,4-hexadiyne monohydrate (2) and of the π···π and C-H···π interactions present in 1,6-bis(1-benzimidazolyl)-2,4-hexadiyne (5) (9 pages), TGA and DSC curves of 2 up to 450 °C (Figure S3), Raman, UV-vis, and infrared spectra of 4 a...
متن کاملSome Aspects of Solid State Polymerization
Previous investigations on solid state polymerization are reviewed, and a few examples of new experimental results are added. Radiation-induced polymerizations of methyl methacrylate in the supercooled liquid phase, and of cyclohexene oxide in the plastic crystalline phase, have been examined. Polymerizations of acrylamide and N-vinylcarbazole were investigated on a solid surface with initiatio...
متن کاملStructural Aspects of the Topochemical Polymerization of Diacetylenes
The present state of knowledge of the topochemical polymerization of diacetylenes is reviewed with regard to structural properties. Principles and mechanisms of topochemical reactions are described. Solid-state polymerization of diacetylenes utilizes the special packing properties of monomer units in their crystals. Rules relating reactivity in the solid-state and packing properties are given a...
متن کاملThe Effect of Spacer Length on the Polymerization of Diacetylenes in SAMs on Gold Surfaces
The influence of the molecular architecture of diacetylene disulfides on the structure and polymerizability of self assembled monolayers on gold was investigated. The position of the diacetylene group was varied systematically by adjusting the length of the tail and the spacer. For the strutures studied, the longer the tail, the higher the akyl chain crystallinity as sensed by IR spectroscopy, ...
متن کاملMechanochemical solid-state polymerization. VIII. Novel composite polymeric prodrugs prepared by mechanochemical polymerization in the presence of pharmaceutical aids.
We carried out the mechanochemical polymerization of methacryloyl derivatives of acetoaminophen and 5-fluorouracil in the presence of lactose. The reaction proceeded readily and the polymeric prodrugs were quantitatively produced. This method produces powdered polymeric prodrugs in which fine particles of lactose are homogeneously dispersed, since the reaction proceeds quantitatively through a ...
