The optical properties of an imidazole derivative were studied at various pH values and in solvents and the solid-state through experimental and DFT calculation.

Aryl and alkyl chiral oxazolidine sulfonium salts with cis and trans dispositions derived from (–)‐(R)‐2‐phenylglycinol were demonstrated to be good to excellent chiral auxiliaries for the diastereoselective synthesis of (2R,3S)‐trans‐epoxyamides. Interestingly, the diastereoselective outcome depends on the stereochemistry of the chiral center at the C‐4 position of the oxazole moiety. The stereoselectivities were consistent even for aliphatic aldehydes.

A low molecular weight fluorescent malononitrile derivative showed an efficient solid-state emission and electroluminescence properties.
