Abstract: The present disclosure relates to dibenzoxanthene compounds that are efficient quenchers of fluorescence, for example in the far red and near infrared spectrum. Applications using the dibenzoxanthene quenching compounds and methods of making same are also described. Also disclosed is a method of detecting or quantifying a target nucleic acid molecule in a sample by polymerase chain reaction (PCR). The compounds have the following formula (I).
