The photophysical properties and the photoinitiating reactivity of a ditopic alkoxynitrostilbene were compared to those of its single branch chromophore used as a reference. Whereas a trivial additive effect is observed when considering the one- and

Two TICTOID-based pyridinium-phenolates bearing a crown ether macrocycle have been designed for the complexation of a potassium cation. The nucleophilicity of the intraannular phenolate -O(-) function can be strongly modulated by biaryl twisting. Suc

The variable-temperature («dynamic») NMR measurements of series of pyridinyl anisoles and pyridinyl phenols each of them bearing ortho, ortho′ handles of various lengths at oxygenated ring lead to the following results: (i) at room temperature, a

Molecular modelling is a growing science which allows to calculate short range forces between zeolite frameworks and organic compounds. By using a steric approach, it is possible to design templates matching closely with an inorganic framework. Herei

Semi-empirical calculations as well as our preliminary studies indicate an increase of the nonlinear response of pyridinium phenolates with the raise of their interplanar angle. Unfortunately, the tendency of previously synthesized zwitterionic compo
