243 | DF | .~ Heterocyclic ring compound; a heterocyclic ring is one having as ring members only carbon and at least one hetero atom selected from nitrogen and chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) {4} |
268 | | .~.~ The hetero ring contains five members including nitrogen and carbon (e.g., polyvinylpyrrolidone, etc.) {4} |
269 | DF | .~.~.~> Plural hetero atoms in the hetero ring (e.g., pyrazoles, benzimidazoles, etc.) {3} |
287 | DF | .~.~.~> Plural oxygens double bonded directly to ring carbons of the hetero ring which are adjacent to the ring nitrogen {4} |
296 | DF | .~.~.~> Polycyclo ring system which contains the hetero ring as one of the cyclos (e.g., indigo, carbazole, phthalocyanine, etc.) |
297 | DF | .~.~.~> Having a -C(=X)X- group, wherein the X's are the same or diverse chalcogens, attached directly or indirectly to the hetero ring by acyclic nonionic bonding (e.g., vinylpyrrolidone-acrylate copolymers, etc.) {1} |
