title: Demonstration of the optical limiting effect for an hemiporphyrazine.
abstract: The hemiporphyrazine complex 9,22-bis(dibutoxy)hemiporphyrazinato chloroindium(III) (1) is one of the few examples for this class of compounds, which displays the nonlinear optical effect of reverse saturable absorption for nanosecond laser pulses in the visible spectrum. The high linear transmission combined with the fast switching into a strongly absorbing excited state in the same spectral range (400-650 nm), renders the studied hemiporphyrazine an ideal material for the passive shuttering of pulsed radiations.
