The spectroscopic properties of single terrylene (Tr) molecules are studied in a polycrystalline matrix of para-dichlorobenzene (p-DCB) at 1.5 K. Samples grown in a glass capillary show a very strong site at 597 nm, which is redshifted by more than 700 cm(-1) from the observed transition energy for Tr in p-DCB prepared as a film on a coverslip (572 nm). Each of these two sites is characterized by measuring their single-molecule spectroscopic parameters at 1.5 K. Lifetime-limited linewidths of 45±5 MHz are found for both sites. Fluorescence detection rates reach 8×10(4) count s(-1) at saturation. The spectral trails of the majority of single molecules show no spectral jumps, indicating an absence of interacting two-level systems; however, the small distribution of linewidths may indicate weak interactions with low-frequency modes. Frequency jumps are observed for 10 % of the molecules. The complete emission spectra from two different single molecules at the center of each of the two sites is presented. Debye-Waller factors of αDW=0.33±0.05 for the normal site (572 nm) and αDW=0.30±0.05 for the red site (597 nm) are reported. This new host-guest system provides a quick and easy way to obtain lifetime-limited single-molecule lines.

Triplet states can be interesting for optical switching of molecular fluorescence as well as quantum experiments relying on the manipulation of spin states. However, the ground state of molecules is usually a singlet state. It is therefore interesting to study the intersystem crossing (ISC) rates between singlet and triplet states. We have measured the autocorrelation function of the fluorescence from single perylene molecules in an ortho-dichlorobenzene host matrix at cryogenic temperatures (1.3 K). We observed two time scales in the autocorrelation function corresponding to intersystem crossing to two indistinguishable triplet states (TX and TY) and a third triplet state (TZ). By studying the power dependence of the correlation times and contrasts in the autocorrelation functions of single molecules, we determine the ISC rates of perylene for the first time.

“…In the mentioned studies, Tr molecules, optically excited to the S 1 state, were capable to emit more than 10 5 uorescence photons before It is well known that the rate of intersystem crossing transition increases in environments possessing heavyatoms [20], by the same talk, these media are responsible for quenching of the molecular uorescence. It was * corresponding author; e-mail: kozank@ifpan.edu.pl therefore surprising that Tr in polycrystalline ortho- [21] and para-dichlorobenzene [22], both host matrices with chlorine as the heavy-atoms, create bright and highly photostable single-molecule systems. Negligible role of the external heavy-atom eect on the Tr emission may be related to much higher triplet state depopulation rate than the rate of its population [6].…”

Results of optical studies of a new single-molecule system, terrylene molecules in a 2,3-dichloronaphthalene crystal, are presented for the rst time. Analysis of the second-order uorescence intensity correlation function shows that the external heavy-atom eect (due to the chlorine atoms) contributes to the increase of the intersystem crossing rate constant for the S1 → T1 transition, by one order of magnitude, whereas the rate constant for the T1 → S0 transition is only weakly inuenced.
