results of the modeling study were confirmed experimentally by cyclic voltammetry to evaluate the substituent effects on the highest occupied molecular orbital (HOMO) and the LUMO of the peropyrene core. The UV−vis absorption spectra of all compounds recorded in trifluoroacetic acid are almost superimposable and display a characteristic visible absorption band between 460 and 490 nm (log ε = 4.64−5

Fluorinated 1-cyclopropyl-7-(substituted-pyridinyl)-1,4-dihydro-4-oxo-3-quinolinecarbo xylic acids of the formula ##STR1## wherein R is hydrogen, R' and R" are hydrogen or fluoro, or other groups and Z is 3- or 4-pyridinyl substituted by alkyl groups or substituted alkyl groups, are superior antibacterial agents. They are prepared via a coupling reaction between the corresponding esters (R=alkyl) having a halo group in the 7-position and a substituted (trialkylstannyl)pyridine.

chalcogen- and halogen-bonding interactions can be used simultaneously to engineer multicomponent co-crystals. Through the rational design of crystallizable molecules, chalcogenazolo pyridine scaffold (CGP) modules were prepared that, bearing either a halogen-bond acceptor or donor at the 2-position, can interact with suitable complementary molecular modules undergoing formation of supramolecular polymers
