Physical chemistry chemical physics : PCCP

Kumar M, Busch DH, Subramaniam B, Thompson WH.
PMID: 25259380
Phys Chem Chem Phys. 2014 Nov 14;16(42):22968-73. doi: 10.1039/c4cp03065f.

The tautomerization of Criegee intermediates via a 1,4 β-hydrogen atom transfer to yield a vinyl hydroperoxide has been examined in the absence and presence of carboxylic acids. Electronic structure calculations indicate that the organic acids catalyze the tautomerization reaction...

Organic Zeolite Analogues Based on Multi-Component Liquid Crystals: Recognition and Transformation of Molecules within Constrained Environments.

Materials (Basel, Switzerland)

Ishida Y.
PMID: 28879985
Materials (Basel). 2011 Jan 11;4(1):183-205. doi: 10.3390/ma4010183.

In liquid crystals (LCs), molecules are confined in peculiar environments, where ordered alignment and certain mobility are realized at the same time. Considering these characteristics, the idea of "controlling molecular events within LC media" seems reasonable. As a suitable...
