Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 14098-44-3, Name is Benzo-15-crown-5, Application In Synthesis of Benzo-15-crown-5.
Four new organic hosts are described that contain a phtalocyanine core to which four crown ether rings are attached.These hosts include a free base phtalocyanine with 18-crown-6 rings and three copper phtalocyanines with 15-crown-5, 18-crown-6, and 21-crown-7 rings.The macrocycles are synthesized from benzo crown ethers in three steps.In solution the phtalocyanines tend to form aggregates.This aggregation is affected by the polarity of the solvent and the presence of alkali-metal salts, which coordinate to the crowns.Cations with diameters that match the diameters of the crown ether rings form 4:4 host-guest complexes with the new hosts.Complexes with 8:4 host-guest stoichometry are formed when the diameters of the cations exceed that of the crown ether rings.Binding free energies of the copper phtalocyanine hosts are presented and compared to those of benzo crown ethers.The binding profiles support the results of UV-vis experiments; i.e., thet large cations induce aggregation of the macrocycles.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application In Synthesis of Benzo-15-crown-5. In my other articles, you can also check out more blogs about 14098-44-3
