Abstract | Polycyclic aromatic hydrocarbons, particularly acenes, are gaining attention as candidates for organic semiconductors. TIPS-pentacene, a functionalized acene with triisopropylsilyl (TIPS) side groups, demonstrates enhanced physical stability, solubility, and superior charge transport properties due to improved molecular packing. This study presents a high-resolution laser-induced fluorescence study comparing TIPS-pentacene and pentacene isolated in helium nanodroplets and attached to solid rare-gas clusters (neon and argon). Our findings reveal distinct differences in the vibronic structures of these molecules, with TIPS-pentacene displaying pronounced vibrational progressions of low frequency vibrational modes of the molecular side groups. The results offer insights into matrix effects and advance our understanding of TIPS-pentacene’s vibronic structure, recently reported to contribute via coherent vibrational wave packets to ultrafast singlet fission processes. |
