A study was conducted to demonstrate the development of volatile- and nonvolatile-type memory elements due to fluorescence switching and based on structural modifications of dye molecules. These memory elements were operated by using fluoride anions as writing components. The study used simple porphyrin derivatives 1 and 2 that possessed four and two redox-active 3,5-di-tert-butyl-4-hydroxyphenyl groups. These derivatives exhibited optical properties, including intense fluorescence of their solutions. Porphyrin derivative 1 was prepared by the condensation of pyrrole with 3,5-di-tert-butyl-4- hydroxybenzaldehyde in propionic acid at reflux, while derivative 2 was prepared by a similar method using a mixture of the appropriate benzaldehydes. Memory cycling of the two derivatives was carried out by a 10-5M solution of 1 in dichloromethane, prepared from a 5×10-4M stock solution and an addition of tetra-n-butylammonium fluoride to the solution.
5,10,15,20-Mesotetrakis(3,5-di-t-butyl-4-quinomethide)porphyrinogen: a Highly Puckered Tetrapyrrolic Macrocycle from the Facile Aerial Oxidation of a Phenolic Porphyrin

The unusually highly puckered macrocyclic core of the title compound confirms proposed conformational changes which are essential for the facile aerial oxidation of phenolic porphyrins, such as meso-tetrakis(3,5-di-t-butyl-4-hydroxyphenyl)porphyrin (1).

Tetrapyrrole macrocycles, of which the pyrroles are connected by sp2 centers, were readily obtained from porphyrin tetraphenols by air oxidation under basic conditions, followed by N-alkylation. The degree of N-alkylation could be controlled and either di
