Abstract:
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.

Abstract:
Nonlinear transmission property of excited state proton transfer molecule 2-(2′-hydroxyphenyl)benzoxazole was investigated at 355 nm and 532 nm using picosecond laser pulses. The experiment result shows that the transmissivity of 2-(2′-hydroxyphenyl)benzoxazole is nonlinear at 355 nm but it is linear at 532 nm. The nonlinear transmissivity of 2-(2′-hydroxyphenyl)benzoxazole originates from the larger nonlinearity of tautomer formed in excited state proton transfer process. Therefore 2-(2′-hydroxyphenyl)benzoxazole might be used as ultrafast optical amplitude limit material.

Abstract:
Two-photon absorption spectra of 2-(2'-hydroxyphenyl)benzoxazole, 2,5-bis(2-benzoxazolyl)phenol and 2,5-bis(2-benzoxazolyl)hydroquinone are modeled by time-dependent density functional theory calculations. In contrast to the linear absorption, where the transitions to the two lowest excited states are leading, the two-photon absorption cross sections are significant for the transitions to higher states which are weak in one-photon absorption spectra. The 2,5-bis(2-benzoxazolyl)phenol and 2,5-bis(2-benzoxazolyl)hydroquinone demonstrate the maximum cross section of about ten times larger than th

Nonlinear refractive indexes n2 of 2-(2′-hydroxyphenyl) benzoxazole (HBO) in three species of solvent (cyclohexane, ethanol and dimethyl sulfoxide) have been determined by using the Z-scan technique.

Through the study on the absorption and fluorescence spectra of HBO in different solvents, we regard that the principal origin of the nonlinear refractive index of HBO is not the thermal effect because of absorption of incident light but the excited state intramolecular proton transfer of HBO und

Abstract:
Cyclic trinuclear homo-metal complexes, [{Fe(L3+2Br)py}3] (1) and [{Mn(L3+2Br)}3(py)2 MeOH] (2), along with a hetero-metal complex, [FeMn2(L3+2H)3(DMF)3] (3), were synthesized using asymmetric ditopic ligands (H3L3+2H: 2-(2-hydroxyphenyl)-6-ol-5-(salicylideneamino)benzoxazole, H3L3+2Br: 2-(2-hydrox-5-bromoyphenyl)-6-ol-5-(5-bromosalicylideneamino)benzoxazole). The molecular structure of 1 is characterized by a tripod structure with three-fold symmetry, where an enantiomer pair forms a dimeric capsule with dimensions of approximately 3 × 1.6 × 1.6 nm3. Complexes 2 and 3, which lack three-fold s
