A systematic investigation of the concept of pre-organization of nonlinear optical (NLO) active chromophoric groups in calix[4]arene derivatives and the influence on the absolute second-order nonlinear optical coefficients is reported. Several calix[4]are

The reaction of a range of quinones 3 with malononitrile in the presence of titanium tetrachloride/pyridine yields dicyanoquinomethides 4, which on reaction wit N,N'-bis(trimethylsilyl)carbodiimide are converted into the corresponding N,7,7-tricyanoquinom
