A metal-organic framework as a flask: photophysics of confined chromophores with a benzylidene imidazolinone core.

ABSTRACT

Photophysics and dynamics of chromophores with a benzylidene imidazolinone core, responsible for emission of green fluorescent protein variants, were studied as a function of host topology by three approaches. Coordinative, non-coordinative, and "fastened" immobilization were utilized to study chromophore emission. Variable-temperature quadrupolar spin-echo 2H NMR spectra are reported.
