Cassette recording : A new class of coumarin–rhodamine through‐bond energy‐transfer (TBET) cassettes with minimal spectral overlap between the donor emission and the acceptor absorption (see picture) show large pseudo‐Stokes shifts (up to 230 nm) and emission shifts (up to 170 nm). The utility of this TBET platform for TBET‐based probe development was demonstrated by a new ratiometric fluorescence pH probe.
