The first hyperpolarizabilities of merocarbocyanines

Peng Wang, You Ming Chang, Yu Xu, Cheng Ye

Research output: Contribution to journalArticlepeer-review


The dot products μgβCT of first hyperpolarizability and ground state dipole moment of two merocarbocyanines were measured experimentally with solvatochromism and compared to the values obtained by AM1/FF calculation. The comparable result was also obtained by the measurement of second harmonic generation (SHG) for LB film of dye II. The μgβCT of dye II is larger than that of the well known NLO chromophore 4-N, N-dimethylamino-4'-nitrostilbene (DANS).
