Hyperpolarizability of molecules of 2-(2'-hydroxyphenyl)benzoxazole and 2,5-bis(2-benzoxazolyl)phenol is calculated by density functional theory quadratic response method for static electric field and hyper-Rayleigh scattering at 532 nm. It is found that 2,5-bis(2-benzoxazolyl)phenol demonstrates the hyperpolarizability about ten times larger than 2-(2'-hydroxyphenyl)benzoxazole. Dominant component of the hyperpolarizability tensor corresponds to the long axis of the molecule.
