| Tetraalkynyl calix[4] arenes with advanced NLO properties (2005) | |||||||||||||
Abstract | |||||||||||||
| Rigid, highly conjugated tetraalkynyl-calix[4]arenes synthesised via Sonogashira coupling give rise to improved second-order hyperpolarizability values as determined by hyper-Rayleigh scattering-a technique that in addition to X-ray crystallography also allows for the conformational analysis of the calixarene structures in solution. | |||||||||||||
