Witryna1 paź 2024 · Abstract. Ultralong room temperature phosphorescence (URTP) is an attractive phenomenon in organic photonics. Polymer-based URTP materials are … WitrynaCoordination complexes and organometallic compounds are also photoreactive. These reactions can entail cis-trans isomerization. More commonly photoreactions result in dissociation of ligands, since the photon excites an electron on the metal to an orbital that is antibonding with respect to the ligands.
