in this work, a low-toxicity antisolvent, sec-pentanol (spa), was employed as a polar auxiliary agent to control the perovskite nucleation and crystal growth process, which can effectively remove the excess n,n-dimethylformamide (dmf) and dimethylsulfoxide (dmso) in the precursor solution at the spin-coating process because of its moderate

the use of auxiliary substances rsc publishing
from the perspective of a formulations chemist, the expression “auxiliary substance” refers to an entirely different set of materials: the additives in formulations that may not be crucial to the functioning of the product but make the product better for the user.
low-toxicity antisolvent as a polar auxiliary agent for high quality,in this work, we employ a low-toxicity antisolvent sec-pentanol (spa) as a polar auxiliary agent to modify the perovskite films, which can effectively regulate the mai·pbi2·dmso intermediate
dual use of a chemical auxiliary: molecularly imprinted,auxiliary-directed biocatalysis is a powerful and relatively benign tool for chemical synthesis. we recently reported the use of theobromine as a chemical auxiliary for directing cyp3a4-catalyzed oxidations with predictable regio-, chemo- and stereo-selectivity (j. am. chem. soc., 2011, 133, 7853).
- What auxiliary substances should a chemist consider?
- While the solvent may be the most obvious “auxiliary substance” to a chemist, there are many other substances that should also be considered. Drying agents, chromatographic column packings, and separation agents (e.g. saline solution, acid/base wash, activated carbon) are other examples of auxiliary substances used during or after a reaction.
- What auxiliary substances are required for a chemical synthesis?
- It depends on whom you ask. The average synthetic chemist, when reading this principle (Fig. 1), would think of all of the auxiliary substances required for a chemical synthesis and subsequent product purification: solvents, drying agents, column packing agents, etc.
- Are there alternative compounds for 8-phenylmenthol auxiliary?
- Because of the widespread utility of the 8-phenylmenthol auxiliary, alternative compounds that are more easily synthesized, such as trans -2-phenyl-1-cyclohexanol and trans -2- (1-pheyl-1-methylethyl)cyclohexanol have been explored.
- What auxiliary agents are used in synthesis and polymerization of monomers?
- Various auxiliary agents used in the synthesis and polymerization of monomers such as resins, fibers, and rubbers are called synthetic additives, including catalysts, initiators, solvents, dispersants, emulsifiers, polymerization inhibitors, regulators, terminators, etc. .
