Abstract:
Six quinoidal compounds terminated by oxindole have been synthesized via selective nucleophilic addition, dehydroxylation, and oxidation. Through the modification of the quinoidal core and terminal benzene rings with fluoride atoms or cyano groups, the LUMO energy levels of the quinoidal compounds can be tuned within the range -4.05 to -4.54 eV. The quinoidal molecules exhibited electron transport behavior and can be used as dopants to dope an oligo(ethylene glycol)-substituted polythiophene.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of...
