摘要: Abstract The synthesis and full characterization of new chromophores with second-order nonlinearities containing thienylpyrrolyl benzothiazolyl moieties are reported. solvatochromic behavior the compounds was investigated. hyperpolarizabilities β derivatives 4 – 6 were measured using hyper-Rayleigh scattering thermogravimetric analysis (TGA) used to evaluate their thermal stability. experimental results indicate that strong nonlinearity is balanced by good stability especially for 6b 6c , making them candidates NLO applications.
