General description

Rhodamine 101 (Rh101) is a highly stable fluorophore in the rhodamine family.

Application

Rhodamine 101 (Rh101, compound 1) has been used:
  • as a reference model for analysing extra fluorochromic properties of rhodamine derivatives
  • as a reference against thioflavin t (ThT) in the determination of ensemble photophysical properties
  • as reference compound for comparing the quantum yields of nanocrystals

Biochem/physiol Actions

Rhodamine 101 (Rh101) is useful as a reference material to measure the fluorescence quantum yield.

Diarylethene derivatives having benzothiophene S,S-dioxide groups undergo turn-on mode fluorescence photoswitching. For the practical application to super-resolution fluorescence microscopy, photoswitchable fluorescent molecules are desired to be resistant against photodegradation. Here we synthesized turn-on mode fluorescent diarylethenes having electron-withdrawing (trifluoromethyl or
