Unveiling the regulation of triplet excitons by intermolecular interactions in 4-phenylmorpholine: Insights from transient absorption spectroscopy and theoretical modeling
{{output}}
Heteroatom-containing derivatives of 4-phenylmorpholine are cost-effective phosphorescent materials. In this study, femtosecond transient absorption (TA) spectroscopy of 4-phenylmorpholine reveals that the excited-state absorption signal at 625 nm decays as th... ...
