Abstract

A series of sodium arylcyclotetrasiloxanolates properly functionalized in the para position of the aromatic ring, like [4-RC6H4Si (O) ONa] 4 and the corresponding (trimethylsiloxy) cyclotetrasiloxanes [4-RC6H4Si (O) OSiMe3] 4 (R= Cl, Br, CHCH2, CH2Cl), were prepared as scaffolds for anchoring second order NLO active or fluorescent organic chromophores. Such cyclic molecules can be regarded as 2D models reproducing supramolecular ...
