Chiroptical spectroscopic techniques based on fluorescence.

Among the various chiroptical spectroscopic methods circular dichroism (CD), optical rotatory dispersion (ORD), Raman optical activity (ROA), the methods based on fluorescence have so far played a marginal role. Fluorescence detected circular dichroism and circularly polarized luminescence (CPL) were both introduced many years ago with important, but not so frequent, applications. In particular, CPL, which requires specialist hardware, has been restricted by the limited number of users. Recent interest, which has increased in the field of material science particularly, where the emission properties are more attractive and important than the absorption ones, has motivated new application fields and may change the situation in the future.
