What is Nonlinear Absorption of New Mesoionic Compounds about?

The nonlinear absorption of new mesoionic compounds (MIC) was investigated using nanosecond laser pulses with wavelengths at 570, 605 and 618 nm. Nonlinear absorption cross-sections, r 2 % 10 À45 cm 4 s/photon, larger than any recorded in the literature, were obtained due to the introduction of p-CF 3 -C 6 H 4 electron-acceptor and p-CH 3 -C 6 H 4 or p-CH(CH 3 ) 2 -C 6 H 4 electron-donor groups in the MIC ring. The large values of r 2 , the ease of synthesis of these compounds and their marked stability, make them promising candidates for photonic applications.
