Excited-State Dynamics of Phenylene Moieties in a Framework of the Organosilica Nanotube

To understand the excited-state dynamics of Ph moieties in a framework of the phenylene–silica nanotube (Ph-NT), temperature and time dependence of the fluorescence were investigated. The time dependence of the Ph exciton fluorescence and excimer fluorescence was successfully analyzed by the model including the diffusion of the Ph excitons and their subsequent trapping at the defect center and the excimer sites. The energy migration of the Ph exciton in the Ph-NT is suggested similarly to phenylene-bridged periodic mesoporous organosilica (Ph-PMO) powder with crystal-like wall structure, although X-ray diffraction of Ph-NT indicates less molecular-level periodicity of Ph moieties in the framework of the nanotube. The excited-state dynamics of Ph moieties in Ph-NT will be discussed by comparing that of Ph-PMO.
