The tumor volume growth rates of the primary tumor (treated with PDT) are presented in Figure 6 e. As compared to Group 3 (only the injection of helical‐BDP‐NPs) and Group 1 (only irradiation with light, hv), the primary tumor in Group 4 (helical‐BDP‐NPs + hv) shows significant inhibition of growth, indicating that helical‐BDP‐NPs is a potent PDT reagent for primary tumors. Hence, we have a true helical π‐system. without permission from the American Chemical Society.

Experimental conditions, synthesis and thermal properties, electrochemical curves, crystal structures, and theoretical calculations (PDF). The parent bodipy (BDP, Figure 1) was used as a control compound throughout this study. Since ISC of organic chromophores is fundamentally important in photochemistry as well as in many other important areas such as PDT, we believe that our study not only leads to the discovery of new heavy atom‐free photosensitizer molecular structural motifs with unique triplet properties, it also opens up a wide variety of opportunities in photonic/biophotonic fields.

Moreover, the vibrational progression of the helical‐BDP is more resolved than that of the BDP.

In this study, we got inspiration from distorted conjugated systems, which display elevated ISC efficiency.18-26 In particular, the removal of the mirror‐plane symmetry of a planar π‐system is considered to allow for a stronger spin orbit coupling (SOC) between π–π* states with different spin manifolds (the singlet state and triplet state), hence facilitating ISC.27 The most notable exemplar molecule is the buckminsterfullerene (C60), which has a heavily curved π‐conjugation skeleton.

One direct transition is phosphorescence, where a radiative transition from an excited triplet state to a singlet ground state occurs.This is also a very slow, forbidden transition.

A careful simulation reveals an overpopulation of the Tx state (Figure 4 c). Herein, we report the co‐existence of efficient ISC and long triplet excited lifetime in a heavy atom‐free bodipy helicene molecule. The twisted bodipy shows intense long wavelength absorption (ϵ=1.76×105 m−1 cm−1 at 630 nm), satisfactory triplet quantum yield (ΦT=52 %), and long‐lived triplet state (τT=492 μs), leading to unprecedented performance as a triplet photosensitizer for PDT.
