3-Cyanopyridines containing an acetyl, ester, nitro, or cyano group in the 5-position were synthesized via various versions of the Hantzsch reaction. Recyclization of quaternary pyridinium salts by the action of aqueous-alcoholic alkali afforded 2-methylaminopyridine derivatives and 6-methylamino-3-nitro-2,4-diphenylbenzonitrile.

values of some compounds are on the order of 10−48 cm4 s photon−1. These chromophores also have relatively high two-photon-excitedfluorescence (TPEF) action cross sections. Pumped by the laser at 800 nm, these chromophores show efficient two-photon-induced orange-red fluorescence emission. The experimental results indicate that the different end-capped functional electronic donors and the number of
