Synthesis of polymethine dyes possessing nonlinear optical properties and preparation of photoconducting systems based thereupon
Reactions of 2,3,3-trimethyl-3H-indolium and 2-methylquinolinium quaternary salts with o- and p-hydroxybenzaldehydes afforded polymethine dyes (styryls) which were isolated for the first time as the corresponding tetrafluoroborates. The dyes can redily be
