Table 1.

Measured and calculated values of absorption maxima in UV-Vis spectra of cis-styryl-thiophene benzylamines, along with transitions responsible for λ_max. Calculated data were obtained at the computational model (CPCM)TD-CAM-B3LYP/6–31++G(d) (ACN), with geometries optimized at the M06-2X/6-31G(d) level of theory. The highest occupied and lowest unoccupied molecular orbital are denoted by H and L, respectively.
