Heterocyclic derivatives of long-chain diacetylenic acids

Acyl derivatives of 2-aminopyridine, 2-aminopyrimidine, 4-amino-2,2,6,6-tetramethylpiperidine-1-oxyl, and 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl were obtained form long-chain diacetylenic acyl chlorides and the corresponding heterocyclic compounds.Spreading isotherms of monolayers on a water surface show that lengthening of the hydrocarbon chain and replacement of the pyridyl groups in these compounds by the more hydrophilic pyrimidyl groups render the films more condensed.Long-chain acyl derivatives of nitroxyl radicals form monolayers possesing a low collapse pressure.ESR spectra on Langmuir-Blodgett films of these radicals before and after photopolymerization were recorded. - Keywords: long-chain diacetylenic acids, N-pyridyl and N-pyrimidylamides of alkanediynic acids, long-chain derivatives of nitroxyl radicals, synthesis, monolayers, Langmuir-Blodgett films

Polyacetylenic lipids, radiation-sensitive compositions, photographic elements and processes relating to same

A photopolymerizable monomer comprising a lipid having at least one hydrophobic acyl chain containing at least two conjugated acetylenic linkages is useful in preparing radiation-sensitive compositions and photographic elements comprising a plurality of liposomes. Further, processes for photopolymerizing the radiation-sensitive compositions and for forming an image in the photographic elements comprise exposing the lipid to radiation, heating the lipid to a temperature equal to or above a first transition temperature of the lipid to render it insensitive to further exposure, and optionally cooling the lipid to a temperature equal to or below a seocnd phase transition temperature of the lipid to render it again sensitive to further exposure. The monomeric lipids, when photopolymerized, form polymeric lipids exhibiting decreased solubility and liposome wall permeability as compared to the unpolymerized monomeric lipids.
