Based on a bent-core NLO-phore with a μβ0 in the range of 390 × 10-48 esu (1907 nm), the second order susceptibility tensor for second harmonic generation is evaluated at excitation wavelengths of 1064 and 1600 nm in a mesogenic material with a SmCP mesophase. The NLO coefficients are in the range 10-100 pm V-1. Thus it is deduced that a molecular design leading to bent-core liquid crystals with large β values is a correct strategy to achieve NLO-materials for bulk second order effects. © The Royal Society of Chemistry. | URI: | http://hdl.handle.net/10261/52338 | DOI: | 10.1039/B923616C | Identificadores: | doi: 10.1039/B923616C issn: 0959-9428 e-issn: 1364-5501 |
