[HTML][HTML] Synthesis and photophysical properties of novel succinimidyl benzazole derivatives, evaluated by Candida albicans ATCC 10231 fluorescent staining

RC dos Santos, NV da Silva Faleiro, LF Campo… - Tetrahedron letters, 2011 - Elsevier
New fluorescent succinimidyl benzazole derivatives were synthesised and successfully
used to stain Candida albicans ATCC 10231 cells. The dyes were characterised by means
of infrared, 13 C and 1 H NMR spectroscopies and elemental analysis. UV–Vis and steady-
state fluorescence in solution were also applied to characterise their photophysical
behaviour. The novel dyes were fluorescent in the yellow–green region by a
phototautomerism in the excited state (ESIPT) with a large Stokes shift (9065–10962 cm− 1) …
