## Abstract The synthesis of two new flavin substituted calix[4]arene derivatives, **9** and **10**, is described. The first flavin substituted calix[4]arene derivative **9** was synthesized by the reaction of 3โmethylalloxazine (**5**) with 25,27โbis(3โbromopropoxy)โ26,28โdihydroxyโ5,11,17,23โtetr

## Abstract The new chromophore compounds with NLO properties were prepared by Knoevenagel condensation from formyl or diformyl calix[4]arene and isophorone derivatives in the presence of piperidine and acetic acid, respectively. In these chromophore calix[4]arenes, the ring locked trienes were emp
