In substituted calix-arenes-cyclophanes consisting of four phenol moieties connected by methylene bridges-the number and also the relative positions of the donor and/or acceptor pi- conjugated (D-pi-A) units can be varied by changing the configuration. The Figure illustrates the cone configuration. The molecular and thin-film NLO properties of three tetra-D-pi- A-substituted calixarenes, including their orientation in thin films and the stability of their NLO properties, are described.
