Synthesis and Spectroscopic Characterization of 2-(het)Aryl Perimidine Derivatives with Enhanced Fluorescence Quantum Yields

Synthesis, crystal structure, and optical properties of fluorinated poly(pyrazole) ligands andin silicoassessment of their affinity for volatile organic compounds

“…The fluorescence quantum yield values were also evaluated by comparison with dimethyl-POPOP in cyclohexane (fluo = 0.96), as described in detail elsewhere. 72 The quantum yields, reported in the fourth column of Tables 1-4, do not exhibit a straightforward trend with either solvent polarity or fluorination degree. This occurrence, together with the environment-independent spectral features, might be beneficial in view of application to VOCs sensing, as the fluorescence signal is expected to be robust with respect to environmental perturbations other than - stacking with the VOCs aromatic ring, including self-assembly within a MOF.…”
