The frequency-doubling of 820 nm laser light is one of the properties of a series of nitrocalix-arenes making them suitable, in principle, for the construction of a blue laser. Derivative 1 is the most promising, since it displays the greatest hyperpolarizability and the largest dipole moment and is stable as a film in a polymer matrix for long periods.
