--- _id: '7300' abstract: - lang: eng text: Photoinduced electron transfer (PET), which causes pH-dependent quenching of fluorescent dyes, is more effectively introduced by phenolic groups than by amino groups which have been much more commonly used so far. That is demonstrated by fluorescence measurements involving several classes of fluorophores. Electrochemical measurements show that PET in several amino-modified dyes is thermodynamically favorable, even though it was not experimentally found, underlining the importance of kinetic aspects to the process. Consequently, the attachment of phenolic groups allows for fast and simple preparation of a wide selection of fluorescent pH-probes with tailor-made spectral properties, sensitive ranges, and individual advantages, so that a large number of applications can be realized. Fluorophores carrying phenolic groups may also be used for sensing analytes other than pH or molecular switching and signaling. article_processing_charge: No article_type: original author: - first_name: Daniel full_name: Aigner, Daniel last_name: Aigner - first_name: Stefan Alexander full_name: Freunberger, Stefan Alexander id: A8CA28E6-CE23-11E9-AD2D-EC27E6697425 last_name: Freunberger orcid: 0000-0003-2902-5319 - first_name: Martin full_name: Wilkening, Martin last_name: Wilkening - first_name: Robert full_name: Saf, Robert last_name: Saf - first_name: Sergey M. full_name: Borisov, Sergey M. last_name: Borisov - first_name: Ingo full_name: Klimant, Ingo last_name: Klimant citation: ama: Aigner D, Freunberger SA, Wilkening M, Saf R, Borisov SM, Klimant I.
