摘要: We investigate the influence of interchain interactions on photoluminescence processes in a sexithiophene single crystal by applying hydrostatic pressure. perform transient spectroscopy time domain 100 fs for pressures up to 60 kbar. The combined use steady-state and time-resolved optical spectroscopies allows us show that pressure-induced quenching is caused an ultrafast (approximately fs) formation intermolecular species.
