Semiempirical methods were applied to the design of a new second order nonlinear optical (NLO) dye through noncentrosymmetric modifications to the symmetric dipyrromethene boron difluoride chromophore. Computational evaluations of candidate structures suggested that a synthetically accessible methoxyindole modification would have second order NLO properties. This new dye consists of 4 fused rings, is soluble in polar organic solvents and has a large molar extinction coefficient (86 {times} 103). Its measured hyperpolarizability, {beta}, is -44 {times} 10{sup {minus}30} esu at 1367 nm. The methoxyindole therefore induces moderate asymmetry to the chromophore.
