New tricyanopyrroline (TCP) chromophores with rigid–flexible dendron were prepared for second‐order nonlinear optical (NLO) application. The chromophores were fully characterized using ultraviolet‐visible spectroscopy, nuclear magnetic resonance spectroscopy and mass spectrometry. Thermal gravimetric analysis (TGA) revealed that the chromophores had excellent thermal stability. Large λ max and high solvate chromic effects revealed that the chromophores had large second‐order optical nonlinearity. The electro‐optic coefficients ( r 33 ) were measured in the chromophores‐doped poly(bisphenol A carbonate) films at the fundamental wavelength of 1310 nm, and the highest γ 33 achieved was 217 pmV −1 .
