Disclosed are infrared light absorbing aminium and diimmonium compositions that have at least one absorption maximum in the infrared spectral region between about 700 and 1500 nm and that are useful, for example, as infrared absorbers. In one example, an infrared light aminium absorbing composition includes an anionic borate moiety and an aminium radical cation, which has at least one absorption peak in the near infrared wavelength region between about 700 and 1500 nm. In another example, an infrared light diimmonium absorbing composition includes two anionic borate moieties and a diimmonium radical cation, which has at least one absorption peak in the near infrared wavelength region between about 700 and 1500 nm. Such compositions may be incorporated into films or bulk materials to form light filters for electromagnetic radiation, including laser radiation.
